                           INDEPENDENT CONTRACTOR AND
                        PROPRIETARY INFORMATION AGREEMENT

This Agreement dated as of July 1, 2003, is by and between Superior Galleries,
Inc., a Delaware corporation, (the "Company"), and Stephen Deeds, Inc., a
California corporation, (the "Contractor"), as follows:

1.       CONTRACTOR STATUS. The parties agree that Contractor is acting as an
         independent contractor to assist the Company to manage the Company's
         public auctions of rare coins. Contractor does not have an employment,
         joint venture, or partnership relationship with Company, and shall not
         represent to any third party that Contractor has authority to bind the
         Company to any contract or commitment other than consignment agreements
         subject to the approval of the Company.

2.       INSTRUCTIONS/CLIENT PROTECTION. Contractor shall have the discretion to
         decide how he performs any work for the Company. However, Contractor
         shall not obligate the Company to any price, credit, commission or
         other terms with clients without the Company's approval, and in
         addition (a) Contractor shall not make any unfair, deceptive or
         misleading statements to clients regarding the Company and its
         products, or (b) omit any material facts so as to make literally true
         statements deceptive or misleading. Without limiting the generality of
         the foregoing, Contractor agrees to comply fully with California
         Business and Professions Code ss.17511 et seq. (the "telephonic seller"
         law), and 16 C.F.R.ss.310 et seq. (the FTC's Telemarketing Sales Rule)
         in any transactions with the Company'S actual or prospective customers,
         and to adhere to the Company's Due Diligence policies as adopted from
         time to time during the term of this Agreement. Contractor agrees to
         indemnify the Company for any loss or damage (including attorney's
         fees) incurred by it as a result of any violation of Contractor's
         obligations under this Paragraph.

3.       TRAINING. Contractor shall not be required to attend any training
         sessions with Company personnel, and Company relies upon Contractor's
         prior experience and contacts in the rare coin marketplace.

4.       CONTROL/EXPENSES. Contractor acknowledges that his services are not
         controlled by Company, and that Company's success in business is not
         dependent upon those services. Company does not require Contractor to
         work only during fixed hours or at Company's place of business, or to
         conform strictly to routines, schedules and work patterns established
         by Company. Rather, Contractor is free to work at his own schedule, and
         to use such equipment and assisting personnel as he deems necessary (at
         his own expense). The Company agrees to provide Contractor with leads
         and marketing support and reimbursement for actual and reasonable
         out-of-pocket travel and entertainment expenses incurred by Contractor
         directly in connection with his services for the Company, but
         Contractor is solely responsible for any office and/or employee
         expenses connected with his services consumed outside of the personnel
         and offices that may be made available from time to time by the
         Company.

                                       6

5.       COMPENSATION. Contractor shall be paid compensation as follows: (a) a
         monthly fee of $19,250, payable in two equal installments on the 15th
         and 30th of each month hereunder, and (b) a commission equal to five
         (5.0%) percent through August 31, 2003 and ten percent (10.0%)
         thereafter of the Company's Net Commissions and Buybacks excluding
         commissions earned from the sale of Superior owned inventory. For
         purposes of this Agreement, "Net Commissions and Buybacks" shall be
         defined as the Company's gross commissions plus buyback fees earned
         from rare coin auctions minus finder's fees paid by the Company.

6.       TERM/TERMINATION. This Agreement shall continue for a term of twelve
         (12) months. Either party may terminate this Agreement on 60 days'
         written notice to the other. In the event of termination, each party
         agrees to pay the other promptly any sums due under this Agreement, and
         Company specifically agrees that Contractor shall be entitled to
         commissions in accordance with Paragraph 5 for any auctions taking
         place within 60 days following the effective date of the termination.

7.       NON-DISCLOSURE OF INFORMATION. Contractor acknowledges that the list of
         Company's customers, as it may exist from time to time, and Company's
         policies and processes are valuable, special and unique assets of
         Company's business. Accordingly, Contractor will not, during or after
         the term of his relationship with Company, disclose the list of
         Company's customers or any part thereof, or any numismatic policy or
         process employed by Company, to any other person, firm, corporation or
         any other entity for any reason or purpose whatsoever.

8.       RETURN OF DOCUMENTS AND RECORDS. Contractor agrees that upon
         termination of this Agreement it shall return to the Company any
         documents, records, notebooks, computer software or diskettes, and any
         other repositories of or containing any information obtained in
         connection with Contractor's relationship with Company, including any
         and all copies thereof, then in Contractor's possession, whether
         prepared by Contractor or third parties.

9.       NON-SOLICITATION OF CUSTOMERS. Contractor agrees that during the term
         of this Contract it shall not directly or indirectly solicit or accept,
         or assist in the solicitation or acceptance of, any business involving
         the purchase or sale of rare coins from any customer or prospective
         customer of the Company except in accordance with this Agreement.
         Contractor further agrees that for a period of one (1) year after the
         termination of this Agreement, it shall not directly or indirectly
         solicit or accept, or assist in the solicitation or acceptance of, any
         business involving the purchase or sale of rare coins from any person
         who was a customer or prospective customer of the Company at the time
         of termination, PROVIDED, HOWEVER, that Contractor shall be free to do
         business with any customer or prospective customer of whom it became
         aware other than through the Company, or which it generated through its
         own leads during the term hereof or those customers that the Stephen
         Deeds, the President of Contractor has had a business relationship
         prior to July 6, 2001 or those customers common to the rare coin trade.

                                       7
<PAGE>

10.      NON-INTERFERENCE WITH BUSINESS. The parties mutually agree that during
         the term of this Agreement and for a period of one (1) year thereafter,
         neither shall attempt to or disrupt, damage, impair or interfere with
         the other's business whether by way of interfering with or soliciting
         its employees, soliciting relationships with independent contractors,
         agents, representatives, vendors and customers, or otherwise, of the
         Company.

11.      BREACH OF RESTRICTIVE COVENANTS. Violation of any of Paragraphs 7-10
         hereof will cause the other party irreparable harm and loss which
         cannot be reasonably or adequately compensated by damages in an action
         at law. Accordingly, in the event of a breach or threatened breach by
         either party of any of the provisions of said paragraphs, the other
         party shall be entitled to injunctive and other equitable relief to
         prevent or cure any breach or threatened breach thereof.
         Notwithstanding the foregoing, the parties shall have other legal
         remedies as may be appropriate under the circumstances including, but
         not limited to, recovery of damages occasioned by such breach. In the
         event that a court of competent jurisdiction determines any of the
         provisions of Paragraphs 7-10 hereof to be unreasonable in scope, time
         or geographic reach, that court is hereby authorized by Contractor and
         the Company to enforce the same in such narrower scope, shorter time or
         smaller geographic reach as the court determines to be reasonable under
         all the circumstances.

12.      ENTIRE AGREEMENT/AMENDMENT. This Agreement constitutes the entire
         agreement of the parties with respect to its subject matter and
         supersedes all prior and contemporaneous agreements and understandings
         of the parties. This Agreement cannot be modified, waived, assigned, or
         transferred without the express written consent of both parties.

13.      BINDING ON SUCCESSORS/NO ASSIGNMENT. This Agreement is binding upon the
         parties thereto and their affiliates, subsidiaries, parents,
         successors, and representatives. This Agreement may not be assigned by
         either party without the other's express written consent and any
         purported assignment without consent shall be null and void.

14.      SEVERABILITY. If any provision of this Agreement is found invalid or
         unenforceable, that provision will be enforced to the maximum extent
         permissible, and the other provisions of this Agreement will remain in
         force.

15.      CALIFORNIA LAW/FORUM. This Agreement shall be construed and enforced in
         accordance with California law, excluding choice of law rules. Any
         dispute arising under or relating to this Agreement shall be submitted
         to arbitration under the Commercial Arbitration Rules of the American
         Arbitration Association, with venue in Beverly Hills, California, and
         the parties agree that the prevailing party shall be entitled to an
         award of its attorney's fees and costs, whether or not those are
         otherwise recoverable by statute. Judgment on any arbitration award may
         be entered in any court of competent jurisdiction.
