1. Significant Accounting Policies

   Principles of Consolidation

   The condensed consolidated financial statements for the three-month and
   nine-month periods ended March 31, 1999, includes the accounts of our
   predecessor corporation, Professional Coin Grading Service, Inc. (PCGS) and
   its majority-owned subsidiaries, Superior Sportscard Auctions (Superior) and
   Internet Universe (IU), in which PCGS had a 60% and 55% ownership interest,
   respectively. The consolidated financial statements for the three-month and
   nine-month periods ended April 1, 2000, include the accounts of PCGS and the
   accounts of Lyn F. Knight Rare Coins, Inc. and Kingswood Coin Auctions, which
   were acquired on February 5, 1999, and Bowers and Merena from the date of
   acquisition, April 11, 2000. In addition, on February 5, 1999, we acquired
   the remaining ownership interests in Superior and IU, which resulted in the
   full consolidation of these entities from the date of acquisition. All
   significant intercompany accounts and transactions have been eliminated in
   consolidation.

   Unaudited Interim Financial Information

   The interim consolidated financial statements as of April 1, 2000, have been
   prepared by Collectors Universe, Inc. ("Collectors" or the "Company")
   pursuant to the rules and regulations of the Securities and Exchange
   Commission (the "SEC") for interim financial reporting. These consolidated
   statements are unaudited and, in the opinion of management, include all
   adjustments (consisting of normal recurring adjustments and accruals)
   necessary to present fairly the consolidated balance sheets, consolidated
   operating results, and consolidated cash flows for the periods presented in
   accordance with generally accepted accounting principles. The consolidated
   balance sheet at June 30, 1999, has been derived from the audited
   consolidated financial statements at that date. Operating results for the
   three-month and nine-month periods ended April 1, 2000, are not necessarily
   indicative of the results that may be expected for the year ending July 1,
   2000. Certain information and footnote disclosures normally included in
   financial statements prepared in accordance with generally accepted
   accounting principles have been omitted in accordance with the rules and
   regulations of the SEC. These consolidated financial statements should be
   read in conjunction with the audited consolidated financial statements as of
   and for the fiscal year ended June 30, 1999, and accompanying notes, included
   in the Company's Prospectus dated November 4, 1999, filed with the SEC under
   Rule 424(b) of the Securities Act of 1933. Certain prior period amounts have
   been reclassified to conform to the current period presentation.

   Use of Estimates

   The preparation of financial statements in conformity with generally accepted
   accounting principles requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of revenues and expenses during
   the reporting period. Actual results could differ from those estimates.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

     The following "Management's Discussion and Analysis of Financial Condition
and Results of Operations" includes "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995. This Act
provides a "safe harbor" for forward-looking statements to encourage companies
to provide prospective information about themselves so long as they identify
these statements as forward-looking and provide meaningful cautionary statements
identifying important factors that could cause actual results to differ from the
projected results. All statements other than statements of historical fact we
make in this Form 10-Q are forward-looking. In particular, any statements that
we make in this Form 10Q regarding industry prospects or our future results of
operations or financial position are forward-looking statements. Forward-looking
statements reflect our current expectations and are inherently uncertain. Our
actual results may differ significantly from our expectations. The section
entitled "Additional Factors That May Affect Future Results" describes some, but
not all, of the factors that could cause these differences.

OVERVIEW

     Collectors Universe provides authentication and grading services for rare
coins and sportscards and authentication services for autographs. In most
instances, fees for authentication and grading services are prepaid. We also
conduct Internet, telephone and in-person auctions of rare coins, sportscards,
sports memorabilia, rare currency, rare records and other high-end collectibles.
Generally, collectibles constituting approximately 65% of the aggregate sales
prices of collectibles sold at our auctions are consigned to us by third
parties, and the other approximately 35% is comprised of collectibles that we
purchase for resale at our auctions. We receive commissions, usually both from
sellers and buyers, when the consigned collectibles are sold and we record the
sale prices of purchased collectibles as revenues when they are sold.

     The gross margin on sales of consigned collectibles is significantly higher
than the gross margin on sales of purchased collectibles, because we realize
commissions on sales of consigned collectibles without having to incur any
significant associated costs. By contrast, upon the sale of purchased
collectibles, we record the costs of acquiring those collectibles, which are
usually a significant percentage of the selling price. As a result, the sale of
purchased collectibles reduces our overall auction margins to a level that is
below that realized for authentication and grading services. Consequently, our
gross margin in future periods will depend not only upon the mix between auction
revenues and grading revenues, but also upon the mix between consigned
collectibles and purchased collectibles sold at our auctions.

     We incorporated in 1986 under the name Professional Coin Grading Service,
Inc., which we usually refer to as "PCGS". In February 1999 we incorporated
Collectors Universe, Inc. in Delaware to become the parent holding company of
PCGS and to acquire (i) the currency auction business of Lyn F. Knight Rare
Coins, Inc. ("Lyn Knight Currency Auctions"), (ii) the coin auction business of
Kingswood Coin Auctions ("Kingswood"), and (iii) the minority ownership
interests in two of our majority-owned subsidiaries, Superior Sportscard
Auctions ("Superior") and Internet Universe ("IU"), thereby increasing our
ownership in those two subsidiaries to 100%. The primary purpose of those
acquisitions was to expand the variety of collectibles that we sell, bring us
additional expertise from the former owners of these businesses, who continue to
manage the acquired businesses for our Company, and add to our customer base and
sources of supply. Those acquisitions were completed in a single transaction,
effective as of February 5, 1999, by means of a reorganization intended to
qualify for non-recognition treatment under Section 351 of the Internal Revenue
Code of 1986. In the reorganization, Collectors Universe paid $2,100,000 in cash
and issued to the owners of the acquired companies an aggregate of 1,689,648
shares of our common stock. Additionally, prior to that reorganization , we were
an "S" corporation for federal and state income tax purposes under the Internal
Revenue Code and, therefore, our income was not subject to federal income taxes
and we paid state income taxes at a statutory rate of 1.5%. The reorganization
resulted in the termination of our status as an "S" corporation, and since
February 5, 1999 we have paid income taxes at corporate rates.

     That reorganization affects the comparability of our operating results for
the quarter and nine months ended April 1, 2000 to our operating results for the
quarter and nine months ended March 31, 1999. Our operating results for the
quarter and nine months ended April 1, 2000 includes the operations of PCGS, Lyn
Knight Currency Auctions, Kingswood, Superior and IU for the entirety of those
periods. In addition, we were taxed at corporate tax rates throughout those
periods. By contrast, although our operating results for the quarter and nine
months ended March 31, 1999 includes the operations of PCGS and a portion of the
operations of Superior and IU for the entirety


                                       10
<PAGE>   11

of those periods, they include the operations of Lyn Knight Currency Auctions,
Kingswood and all of the operations of Superior and IU for only about seven
weeks. Additionally, we had to provide for income taxes at corporate tax rates
for only the last seven weeks of those periods of 1999 and, as a result, our
effective tax rates for the quarter and nine months ended March 31, 1999, were
only 13% and 10.9%, respectively, as compared to 45.5% and 48.2%, respectively,
for the corresponding periods of fiscal 2000.

     Additionally, on March 11, 2000, we purchased substantially all of the
assets of the coin auction and retail coin businesses of Bowers and Merena
("Bowers and Merena"), for $8.0 million in cash and 1,000,000 of our shares. As
a result, the operating results of those businesses for the period from March
11, 2000 to April 1, 2000 are included in our operating results both for the
quarter and nine months ended April 1, 2000.

Net Revenues        $12,321        $6,193        $31,048        $14,344

     Net revenues include fees for grading and authentication of rare coins and
sportscards, revenues from sales of purchased collectibles and commissions on
sales of consigned collectibles at our auctions. Net revenues for the third
fiscal quarter and nine months ended April 1, 2000 increased by 99% and by 116%,
respectively, over the corresponding periods of fiscal 1999. Grading and
authentication revenues increased by 29% in the third quarter ended April 1,
2000 to $6,425 from $4,990 in the same quarter of the prior fiscal year and by
50%, to $18,095, in the nine months ended April 1, 2000 from $12,099 in the
corresponding nine months of fiscal 1999. These increases resulted from
significantly higher submission rates for sportscards, while submission rates
for coins were stable and for significantly higher auction revenues. In the
quarter ended April 1, 2000, auction revenue increased by 389% to $5,896 from
$1,203 in the prior year and in the nine months ended April 1, 2000 by 505% to
$12,953 in from $2,245 in the corresponding nine months of fiscal 1999. The
percent of owned collectibles sold at auctions increased to approximately 45%
for the quarter ended April 1, 2000 and was approximately 35% for the nine
months ended April 1, 2000. The acquisitions of Kingswood and Lyn Knight
Currency Auctions in February 1999, accounted for approximately $1,912 of the
increase in auction revenue in the nine months ended April 1, 2000; and the
acquisition of Bowers and Merena in March 2000 added $639 of auction revenues to
the quarter and nine-month periods ended April 1, 2000.

</TABLE>

     Gross profit is the difference between net revenues and cost of revenues.
Cost of revenues consists of labor to grade coins and sportscards, production
costs, printing, credit cards fees, warranty expense and the cost of purchased
collectibles sold in our auctions. Gross profit margin is gross profit stated as
a percentage of net revenues. Gross profit in the quarter and nine months ended
April 1, 2000 increased by 26% to $5,451 and by 65% to $15,886, respectively.
However, in those same periods the gross profit margin declined to 44.2% and
51.2%, respectively, from 69.8% and 67.1%, respectively, in the corresponding
periods of fiscal 1999. The declines in gross profit margin were primarily
attributable to a change in revenue mix between grading services and auction
revenue, because we realize lower margins on auction sales than we generate on
our authentication and grading services. For the third quarter and nine months
ended April 1, 2000, auction revenue represented approximately 48% and 42%,
respectively, of total revenue compared to approximately 20% and 15%,
respectively for the corresponding periods of the prior year. Also contributing
to lower gross profit margins for the three and nine-month periods ended April
1, 2000 was the sale of approximately $1.1 million of British Royal Sovereign
coins at prices close to their cost.

</TABLE>

     Selling, general and administrative ("SG&A") expenses consist primarily of
wages and payroll related expenses, advertising and promotion, professional and
consulting expenses, travel and entertainment, facility related expenses and
security charges. In the quarter and nine months ended April 1, 2000, SG&A
expenses increased by 25.0% and 59.0%, respectively, as compared to the
corresponding periods of the prior fiscal year, due largely to the growth of our
operations resulting from the business acquisitions completed in February 1999
and in March 2000 and to expenditures to enhance our information systems, to
develop and to obtain content for our website, Collectors.com, and to enhance
our auction capabilities. However, as a percentage of net revenues those
expenses declined to 35.3% and 44.0% in the quarter and nine months ended April
1, 2000, respectively, from 56.2% and 59.9%, respectively for the quarter and
nine months ended March 31, 1999, primarily as a result of the economies
realized from those acquisitions and the revenue increases realized by our
grading services . Additionally, in the second quarter of the current fiscal
year, certain of our executive officers temporarily reduced or suspended their
salaries. These actions reduced SG&A expenses by approximately $135 for second
quarter of fiscal 2000. At the beginning of the third quarter, salaries for
these executive officers were restored but at lower compensation rates than were
previously in effect. We anticipate that SG&A expenses will increase in
subsequent quarters but will continue to decline as a percentage of net
revenues.

</TABLE>

     Amortization of goodwill consists of goodwill charges relating to our
acquisitions that were completed in February 1999 and in March 2000. The Company
is amortizing goodwill over periods of 5 to 15 years. For the third quarter
ended April 2000, we recorded an expense of $36 for amortization of goodwill
associated with the Bowers and Merena acquisition. In subsequent quarters, the
incremental expense for amortization of goodwill relative to that acquisition
will be approximately $216.

     Stock-based compensation consists of stock-based charges arising from stock
options granted after June 30, 1999, and prior to the consummation of the
Company's initial public offering in November 1999, at an exercise price that
was lower than the initial public offering price of the shares sold in that
offering.

</TABLE>

     Interest income on cash and cash equivalents increased because of higher
cash balances which include the net proceeds of approximately $21.4 million from
the sale of 4 million shares of common stock in our initial public offering that
was completed in November 1999. In March 2000 we used $8 million of those cash
balances as partial consideration for the acquisition of Bowers and Merena which
reduced our cash balances to approximately $13.8 million at April 1, 2000.
Accordingly, we anticipate that we will generate reduced interest income in
subsequent periods.

</TABLE>

     For the fiscal year ended June 30, 1999, we recorded minority interest
income of $16 for the third quarter and a minority interest charge of $28 for
the nine-month period resulting from the Company's elimination of minority
ownership in Internet Universe, LLC and in Superior Sports Auctions, LLC. We
acquired the minority interests in both of these entities in February 1999. As a
result, there is no charge for minority interests in the quarter or nine months
ended April 1, 2000.

Income Taxes

     Prior to February 5, 1999, we were an S corporation for federal and state
income tax purposes. As such, federal income taxes were payable by our
stockholders individually and no provision for federal income taxes was
recorded. A provision for California franchise tax was provided at the statutory
rate of 1.5%, which is assessed against all California based S corporations. On
February 5, 1999, we became a C corporation for federal income tax purposes and,
as a result, since that date we have the obligation to pay federal and state
income taxes at applicable corporate rates of taxation. For the three and
nine-month periods of the current fiscal year, we provided for income taxes at
rates of 45.5% and 48.2%, respectively. These current year provisions for income
taxes also reflect the non-deductibility of certain goodwill amortization
charges and certain other permanent timing differences. For the three and
nine-month periods of fiscal 1999, we provided for income taxes at a rate of
13.0% and 10.9%, respectively, because we were an S corporation until prior to
February 5, 1999 and we had to provide for income taxes at corporate rates for
only the last seven weeks of those periods.

LIQUIDITY AND CAPITAL RESOURCES

     At April 1, 2000, we had cash and cash equivalents of $13,781 compared to
cash and cash equivalents of $1,852 at June 30, 1999. This increase in liquidity
is the result of the sale, in November 1999, of 4 million shares of common stock
in our initial public offering, the net proceeds of which were approximately
$21.4 million. In March 2000, we used $8 million as partial consideration for
the acquisition of Bowers and Merena. Historically, we have relied on internally
generated funds, rather than borrowings, as our primary source of funds to
support operations. Our grading and authentication services provide us with a
relatively steady source of cash because, in most instances, our customers
prepay for services at the time they submit their collectibles for
authentication and grading. We do not have a credit facility and, accordingly,
do not currently have any borrowing capability.

     Cash used in operating activities was $573 for the nine-month period ended
April 1, 2000, as compared with cash provided by operating activities of $2,106
for the nine-month period ended March 31, 1999. For the nine months ended April
1, 2000, cash was provided by net income and increases in accounts payable,
increases in income tax payable and non-cash charges for depreciation and
amortization. Cash was used to increase accounts receivable, inventories and
prepaid assets. For the corresponding nine-month period ended March 31, 1999,
cash was provided by net income and increases in deferred revenue and accounts
payable while cash was used to increase accounts receivable and inventories.

     Net cash used in investing activities was $876 for the nine months ended
April 1, 2000, and consisted almost exclusively of expenditures for capital
assets. For the corresponding prior year period, $942 was used for the
acquisition of fixed assets and an advance on a note receivable.

     Net cash provided by financing activities was $13,378 for the nine months
ended April 1, 2000, and consisted of the net proceeds from our initial public
offering and the proceeds from the exercise of stock options. During that
nine-month period, the Company used $300 to pay the remaining purchase price of
the businesses acquired in February 1999 and used $8 million as partial
consideration for the acquisition of Bowers and Merena. In the corresponding
nine months of the prior year period, cash was provided by short-term borrowings
and the sale of treasury stock.

     We believe that our existing cash balances and internally generated funds
will be sufficient to finance our operations and financing requirements for at
least the next twelve months. However, our capital requirements will depend on
several factors, including our growth rate, the amount by which we increase
inventories of owned collectibles for auction, capital expenditures for computer
equipment to support e-commerce and various other factors. Depending on our
growth and working capital requirements, we may require additional financing in
the future through equity or debt offerings, which may or may not be available
or may be dilutive to our shareholders. Our ability to obtain additional capital
will depend on our operating results, financial condition, future business
prospects and conditions then prevailing in the relevant capital markets.

RECENT ACCOUNTING PRONOUNCEMENTS

     In January 1998, the Financial Accounting Standards Board ("FASB") issued
SFAS No.130, "Reporting Comprehensive Income"("SFAS No. 130"). SFAS No. 130
requires that all items required to be recognized under


                                       14
<PAGE>   15

accounting standards as components of comprehensive income be reported in a
financial statement that is displayed with the same prominence as other
financial statements. The Company does not have any items of comprehensive
income requiring separate disclosure.

ADDITIONAL FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

     There are a number of factors that could affect our future operating
results and financial condition. Those factors include the factors discussed in
this "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and in the Risk Fact section, on pages 8 to 17 in the Company's
Prospectus dated November 4, 1999, filed with the SEC pursuant to Rule 424(b)
under the Securities Act of 1933, as amended, to which reference is hereby made
for additional information regarding these factors. In particular, among the
factors described in the Prospectus that could adversely affect the Company's
performance include the risk that the popularity of collectibles will decline;
our dependence on the continued growth of commerce on the Internet; the risk
that our operating results will fluctuate; the risk that our auction business
will not become profitable; the risk that we will be unable to sell purchased
collectibles in sufficient time or at a sufficient price to prevent having to
write-down the carrying value of our inventory of collectibles; the inability to
obtain or increases in the cost of obtaining consignments of collectibles for
our auctions; competition from other internet and from traditional auction
companies and from other authentication and grading companies; and the risk that
we will incur unanticipated liabilities under our authentication and grading
warranties.

                           PART II. OTHER INFORMATION

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

     The Company sold a total of 4 million shares of its common stock its
initial public stock offering stock in November 1999. That offering was
registered on a Form S-1 Registration Statement (File No. 333-86449) filed by
the Company with the Securities and Exchange Commission under the Securities Act
of 1933. That Registration Statement was declared effective on November 4, 1999
and the offering the sale of the shares in that offering was consummated on
November 10, 1999. The proceeds of the offering totaled $24,000,000; the
underwriting discounts and other offering expenses totaled approximately
$2,600,000 and, as a result, the net proceeds of the offering to the Company
totaled approximately $21,400,000. In the quarter ended April 1, 2000, the
Company used $8,000,000 of those net proceeds to fund the cash portion of the
consideration paid for the acquisition of Bowers and Merena. An additional
$200,000 of the net proceeds was used to launch the Company's stamp
authentication and grading service. The remaining net proceeds have been
invested in short-term investment grade instruments and are classified as cash
equivalents in the accompanying balance sheet and are available for general
working capital requirements. These uses of the net proceeds do not represent a
material change from the uses thereof described in the Company's Registration
Statement.
