## GROUP I – Frameless design with large sitting eagle in center

Click here to return to the United States Postage Meter Stamp Catalog
* The Group I stamp design was the first used on a massive scale by commercial mailers in the United States. Postage meter use became the dominant form of postage, outstripping the sales of traditional postage, in the 1950s when the Pitney Bowes RF and RT model series (Sub-group IA) were at their height of use.
* All Group I stamps have single circle town mark at left and the value box at right under the eagle's wing at right.
* All Group I stamps are from mechanical meters. Most are multi-value models. Two in Sub-group IA are from single-value models, and all in Sub-group IB are from limited value models.
* Eight sub-groups exist based on the size and shape of the frank.
* Group I meters were first used in January 1940.

#### Sub-group IA – Value box contains "U.S. POSTAGE" underlined at top

* Frank including town mark is 49-50 mm wide by 22 mm tall except for Types IA5.1 through IA5.3 which are slightly wider.
* "U.S. POSTAGE" underlined at top of value box.
* Value box normally 15-15½ mm square but considerably larger for Types IA5.1 through IA5.3 at 17-18 mm wide.
* Meter models: the Model RF series (ten dollar maximum), the Model RT series (one dollar maximum), the Model 2295 (decimal printer), and a forerunner of the Model 5300:
| Model | Postage range | First used |
| RF | .00½ to 9.99½ | Jan 1940 |
| RF-3 | .01 to 9.99 | Nov 1963 |
| RT | .00½ to 1.00 | Jan 1940 |
| RT-2 | .00¼ to 1.00 | Oct 1961 |
| RT-3 | .01 to 1.00 | Nov 1963 |
| RT-4 | .001 to .10 | Mar 1968 |
| RT-8 | single value: 2⅝, 3¾, or 2⅞ | Dec 1962 |
| RT-13/-14 | single value: 05, 06, 08, 10, 13, or 15 | Jun 1964 |
| 2295 | .001 to .999 | 1981 |
| 5300 forerunner | range unknown | 1958 |
* Meter numbers in 100000, 300000, 600000, and 700000 series.
* Earliest known use, January 4, 1940, generated in a Pitney Bowes public demonstration. A stamp dated January 3, 1940 exists but is probably a misdate. The first commercial use of the the IA stamps probably took place in February 1940.

♦ The four dashes indicate that the meter was installed on a "Parcelmatic" machine designed to process packages. The dashes were impressed by bars that helped feed adhesive meter tape through the meter. For an illustration, see Type IC3.1 variety "a".
♦♦ The meter was issued to the O.S.C. Cooperative (Oregon State College Cooperative) in error with a Post Office town mark containing "P" and "O" at the sides. A creative member of the O.S.C. Cooperative with too much time on his hands removed the leg of the "P" and filed a notch in the "O" to yield "O" and "C".
♦♦♦ The meter was issued to the General American Transportation Corporation of New York. A creative employee with too much time on his hands deliberately removed a leg of the "R" in YORK to yield free advertising in the form of "NEW YOPK, a promotional stunt that had zero impact on the company's fortunes.

NOTES:
* For Type IA4.1 designs with meter numbers in the 50000 series, see Group PV, the self-service vending machine stamps.
* Stamps are known with large colon with dots 3½ mm apart. This larger colon was supposedly used only with the RT-3 model (Type IA4.5) which could print whole numbers only. Stamps exist from meters 615035 and 618104 with fractional values ¼ and ½ and also with whole number values showing the larger colon. No explanation is offered.
* Examples of Type IA4.1 are known with surcharges applied separately either by hand stamp or machine. See the example at right.

NOTES:
* This single-value machine was issued to meet the needs of mass bulk rate mailers. The 2⅝ cents value was the first to appear. Bulk mail rate changes in 1964 and again in 1965 necessitated the change of the value to 2¾ cents and 2⅞ cents respectively. The model RT-8 was withdrawn from use in March 1968 when more versatile meters capable of printing fractional rates were placed into use.
* The wavy lines and the value figures are printed by a single solid die rather than from movable denomination wheels.

    Only one meter is known with this value figure format, 607691, GREENSBORO N.C. It is probably the result of a factory mix-up.

IA4.8. Model "RT-4" or "2295" (multi-value), March 1968.

♦ These models were fitted with the Remote Meter Resetting System (RMRS) which came into use in 1979. RMRS allowed the mailer to reset the postage balance via telephone hookup rather than taking the meter to the post office for resetting. They can be identified by their meter numbers in the 2000000, and 3000000 series.
* Meter numbers in 500000, 800000, 900000, 2000000, and 3000000 series.
