Meter stamps essays are experimental designs that were either abandoned or changed in some way before being approved for use. Experimental designs that reach field testing or production intact are known as pre-production proofs.
Meter stamp essays are almost universally rare with some being unique and others unknown in collectors' hands.
In previous editions of the catalog essays were divided into three sub-groups based on the meter model the designs were prepared for (abandoned, eventually sanctioned, or non-USA origin). Because many essays are not associated with any particular meter model the current edition of the catalog abandons that scheme and uses one based on the developmental era in which the essays were introduced, as follows:It is likely that more essays were created than are listed here. Most may be lost forever as meter companies went out of business and their records eventually being lost or destroyed. Others may still exist lurking in company archives or in the memorabilia of active and former employees.

* * *A word about Proofs. Visually they are identical to approved, issued stamps. Those generated before the stamp design was released are technically essays but are categorized as pre-production proofs and are not included in the ESY Group. Collectors should be aware of them however since they are generally quite rare and have significance. See the article about Essays/Specimens/Proofs in the Information for collectors section of the catalog.


==== Sub-group ESY-A: Before meters were approved for general use in 1920 ====
Type ESY-A1 in 2001 editionESY-AA1. Elmer E. Wolf and William A. Scott, 1898.    [—]
In 1898, Elmer Wolf and William Scott experimented with a meter machine that was promoted as offering security from postage theft. No record could be found of it being submitted to the Post Office Department for consideration.
The illustration is from patent drawings. No actual examples of the stamp are known to exist. The stamp would have been printed on horizontal tape displaying the time, date, firm name, postage amount, and accumulated postage used. The machine was capable of printing nine different postage values.
Type ESY-A9 in 2001 editionESY-AA2. Elmer E. Wolf and William A. Scott, sometime between 1913 and 1920.    [RRRR]
Horizontal frameless design with ornamental line of dots and dashes above and below the following text: "UNITED STATES / POSTAGE" at top followed by "CENTS", GOOD & REESE CO", SPRINGFIELD, OHIO". Two shield ornaments containing the number 2 are at the sides. Below the ornamental line at bottom is "REGISTER" and a six-digit number.
Two examples are known, both printed in red.
Type ESY-A2 in 2001 editionESY-AB1.1. Pitney Postal Machine, 1901.    [RRRR]
Fancy double circle design with "UNITED STATES" at top and "POSTAGE" below inside the rings. Four-digit impression counter number in center. Outside the rings at bottom is "LICENSE 160 NUMBER". Value "TWO 2 CENTS" in ornaments at both sides.
Single denomination machine.
Only one stamp is confirmed to exist, printed in pale gray blue on cover. Two other examples are reported to exist, printed on gummed tape.
Type ESY-A3 in 2001 editionESY-AB1.2. Pitney Postal Machine, 1902.    [RRRR]
Similar to Pitney's 1901 circular design but the value ornaments at the sides have been moved to the bottom where they flank a panel containing the postage value spelled out. At bottom are “LICENSE / 264”.
The impression counter number is five digits rather than four.
This stamp is from a multi-denomination machine capable of printing 1, 2 and 5 cent stamps.
A. Hand-drawn image on cover (unique)
B. Die proof in black without the impression counter number, two cent stamp with one cent and five cent segments printed below the complete two cent stamp (unique)
C. Printed in red (four covers exist plus a single sheet with three die proofs with same impression counter number [45407])
D. Die proof in red without the impression counter number (one sheet with three impressions exists)
E. One cent stamp on cover (unique)
Type ESY-A4 in 2001 editionESY-AB2. Pitney Postal Machine, 1903.    [RRRR]
Shield shaped design with "UNITED STATES / POSTAGE" at top and "TWO (2) CENTS" at bottom. Below the shield is "LICENSE / 264". Rectangle at center contains a five-digit impression counter number.
A. The frank has three hollow circles at the sides of the shield. Two examples reported.
B. The frank has the circles filled in, possibly by colored pencil rather than a die change. One example known on cover.
Type ESY-A5 in 2001 editionESY-AB3. Pitney Postal Machine, 1903.    [RRRR]
Double two-lined oval design with "A PENALTY OF $300 IS FIXED / BY LAW FOR USING THIS ENVELOPE TO" in two lines at top and "AVOID PAYMENT OF POSTAGE / ON PRIVATE MATTER." in two lines at bottom. No postage value shows. In the center is a five digit impression counter number.
This "official mail" design was submitted for a test proposed by the Post Office Department. It was rejected as too large for the small envelopes expected to be used for the trial.
It is not known how many, if any, examples of this stamp exist today.
Type ESY-A6 in 2001 editionESY-AC1. American Postage Meter Co., 1913.    [—]
Gummed tape with value figures at top followed by "PARCEL POST", "PERMIT 42", 4-digit impression counter number, "X.Y. CO.", "CHICAGO, ILL.", and the date.
Multi-denomination machine capable of printing 1, 2, and 5 cent values. The tapes were to be in different colors with the value figures applied in black.
The illustration was taken from patent drawings. The color is added. No actual examples of the stamp are known to exist.
Type ESY-B(AA1) in 2001 editionESY-AC2. American Postage Meter Co., 1913.    [—]
Shield shape design with inner rectangle very similar to Type AB1. In fact the appears to be a modification of the same die with town line changed to "CHICAGO,ILL." and with the permit number changed to a solid block. This essay is probably a transitional design toward Type AB2.
The illustration was taken from a newspaper photo. It is unlikely that actual examples exist.Unlisted in 2001 edition
ESY-AC3.1. American Postage Meter Co. (from Arthur Pitney's personal archives), 1919.    [RRRR]
Sheet of paper with two stamp designs hand drawn in ink by Arthur Pitney. One design is circular and closely resembles essay Type ESY-AD3.2 below. The other is similar to Type ESY-AC3.3 below.
   This sheet and the others shown as Types ESY-AC3.2 through AC3.6 are all hand drawn by Mr. Pitney. Only one of each exists.
   All the AC3 series of essays include "CERTIFIED POSTAGE" in their designs. The use of this phrase was unlikely to have meant Certified Mail service but instead to identify the stamps as actual postage. At the time Pitney created these designs he was struggling to convince skeptical U.S. postal officials that a stamp from a postage meter could be trusted and reliable.
Unlisted in 2001 editionESY-AC3.2. American Postage Meter Co. (A is from Arthur Pitney's personal archives. B is pinned to a letter written by Pitney investor Harry G. Seger mailed to Walter Bowes in 1919.), 1919.    [RRRR]
These essays were hand drawn by Arthur Pitney.
Triple concentric circle design with all circles double lined. At top are “U.S. CERTIFIED / POSTAGE”. At center is the date and time. At the sides are two small circles containing the number “2”.
A. Drawn in ink on small sheet, "TWO CENTS PAID / NEW YORK, N.Y." at bottom. In lines below the frank: "PERMIT NO. 1946 / METER NO. 3275 / HUDSON TERM."
B. Drawn in pencil on small sheet, "CENTS PAID / WASHINGTON D.C." at bottom. In lines below the frank: "PERMIT NO. 3912 / METER NO. 6978". Pitney penned a note on this sheet, "I didn't have time to ink this one, but you can see how it would look. A.H.P.".
Only single examples of A and B are known to exist.

==== Sub-group ESY-B: Early competitive development, 1920 to 1938Type ESY-B(BA1) in 2001 edition ====
ESY-BA1. Pitney Bowes (The Postage Meter Company), 1920.    [RRRR]
This is a prototype design that led to the first commercial meter stamp design, Type B1. It looks like a permit stamp of the time with "PERMIT" and number removed from the bottom and "P.40" penned into the vacant spot. Meter number "M.1031" reads up vertically at right.
One example known, 8 cent value without town mark.Type XXX in 2001 edition
ESY-BA2.1. Pitney Bowes (The Postage Meter Company) (from Arthur Pitney's personal archives), 1921.    [RRRR]
This hand drawn essay was dashed off by Arthur Pitney as he began thinking about a stamp design to replace the square (Group B) frank which the Post Office Department disliked due to its close resemblance to non-metered permit stamps of the day.
The top and bottom ribbons evolved into the oval frank found in Group C.
One sheet exists.Type XXX in 2001 edition
ESY-BA2.2. Pitney Bowes (The Postage Meter Company), 1921.    [RRRR]
This is another Arthur Pitney hand drawn essay, this one more structured than Type ESY-BA2.1 and also more closely resembling the oval design (Sub-group CA) that it was leading to.Type XXX in 2001 edition
ESY-BA2.3. Pitney Bowes (The Postage Meter Company), 1921.    [RRRR]
This is one of six two cent essays printed in white on blue paper (as a blueprint) that were produced in Pitney Bowes' efforts to come up with an acceptable replacement for the square Group B design.
Dated June 28, 1921 this one is a double oval inside a rectangular frame which itself is in a larger frame of straight lines at top and bottom that extend outward at the sides.

Value:    2+1 centType ESY-B(CK1) in 2001 edition
ESY-BA4.5. Pitney Bowes (The Postage Meter Company), 1944.    [RRRR]
Although long past the time when Pitney Bowes was searching for a way to add a surcharge slug to fixed value Model M oval stamp dies this Type CA4 stamp has "Adl. 1¢ Pd." slug inside the town mark.
It is anomalous also because the CA4 stamp was produced by a limited value Model "CVS" machine rather than the fixed value Model M.
Meter number 9654.
Dated January 2, 1944.
Essays in the ESY-BA5 series (-BA5.1 through -BA5.13) were created for Pitney Bowes' Model HX meter. Each of the thirteen essays exists either as a hand-drawn image in pencil or ink on tracing paper mounted on card or drawn directly on the card stock in ink. These large essays measure approximately 3½ by 3¾ inches in size. Five of the designs were converted into metal dies which were used to print normal size stamps with town mark.The purpose of these essays is not fully understood. The HX model first came into use in 1932, but the metal die ESY-BA5 essays have year date 1938. The HX model was old technology by that date. It is possible the year date is random and the essays were created in 1932 while working toward an appropriate design for the HX machine. Another possibility is that the dateless engineering drawings were created in 1932 but the steel die printed stamps were produced years later as souvenirs or for another purpose. All the metal die stamps have town mark "EL PASO / TEXAS" and are dated April 11, May 3, or May 11 1938.

ESY-BB2. Mack Postograph Company, 1922.    [RRRR]
Prototype design leading up to Type CC1. The stamp is as Type CC1 except the lines emanating from the sides of the oval are straight rather than curved.
Two cent meter no. 231, permit number 25
Town mark reads "LOS ANGELES / CALIF/"Type ESY-B(BA2) in 2001 edition
ESY-BC1. Mail-O-Meter, 1921.    [RRRR]
The stamp closely resembles Type B1, Pitney Bowes' first stamp approved for general use. The most obvious different is that the meter number, reading up between the town mark and frank, has "MNo" prefix instead of the single letter "M".
Five different machines were used to print the essays:
A. MNo 0001, PERMIT 1, 2 cents
B. MNo 0002, PERMIT 2, 1 cent
C. MNo 0003, PERMIT 3, 2 cents
D. MNo 0004, PERMIT 4, 1 cent
E. MNo 0005, PERMIT 5, 2 cents
Five sets of five stamps on covers are known to exist.
The design was abandoned after the Post Office Department decided the square indicia was inadequate and that an oval frank would replace it.Type ESY-B(CB1) in 2001 edition
ESY-BC2. Mail-O-Meter, 1922.    [RRRR]
This is a preliminary oval meter design leading to Type CB1. It differs from CB1 in that the center contains "PAID / TWO CENTS / METER NO. / 0005" with "PERMIT" and a solid block in the lower panel. The lines at the sides sweep up rather than down as they do with CB1.
Two examples of this stamp are known, one on an unaddressed cover and the other on an addressed cover. Both stamps have the same date and time, September 8, 1922, 11:30 am, and the addressed cover has return address in New York City although the meter stamp shows "DETROIT / MICH." which is where Mail-O-Meter was located. These facts make it unlikely that the addressed cover was actually mailed.Type ESY-C1 in 2001 edition
ESY-BD1. The Automatic Franking Machine Co. Ltd. (AFM) model "E", 1921.    [RRRR]
A sheet exists with several essay designs prepared by Ernest Moss of New Zealand, founder of AFM. The company had considerable success in its home country and in 1921 prepared to expand business into the rest of the world. Two Moss machines were shipped to England that were to be forwarded to the U.S. for testing, but that was never done.
The stamps are upright straight-line rectangles with small breaks low at the sides. At the bottom below the breaks is the town name. Small squares in the upper corners show the postage value. At center is a circled meter number with "POSTAGE" curved over "PAID" above and the postage amount spelled out below.
The sheet contains two sets of essays prepared for the U.S. Each set consists of 20, 10, 5, 2, and 1 cent stamps printed in black. The set with meter number 1 has town name "WASHINGTON". The other set has meter number 2 and town name "NEW YORK". The full sheet is shown at right.

Three impressions are known, one on an official Los Angeles Post Office Department envelope, and two on opposite corners of a plain envelope. All the stamps have the same date, July 22, 1924. The stamps have the appearance of a rubber hand stamp impression and may not have been produced by a meter.Unlisted in 2001 edition
ESY-BF2.1, Whitlock (William J. Pearson), 1928.    [—]
This is a design found on a patent filed by William J. Pearson in 1928. Although no connection with Mr. Pearson and Whitlock could be found the design is obviously a precursor to Type ESY-BF2.2 below which came from Whitlock. Either Pearson worked for Whitlock or Whitlock obtained the patent from him.
Shown reduced at lower right is the illustration as taken directly from the patent drawings. Shown above it is the illustration modified by the removal of the outer rectangle which is not part of the stamp.
The frank consists of four plain rectangles containing the ZONE and number, weight, postage, and "POSTAGE / PAID" respectively with "UNITED STATES POSTAGE" spelled out above. Below the four boxes are two lines of text:
"METER No.______ PERMIT No._____"
"METERED PARCEL POST MAIL"
With double circle town mark at left reading "LOS ANGELES / CALIF"

ESY-BG1. National Cash Register, 1925.    [RRRR]
Group C-like oval design inscribed "INTERNATIONAL" at top and "GENERAL ELECTRIC" at bottom.
Inside the side circles are script "G" and "E".
This appears to be an essay prepared for use as an internal control stamp for General Electric, but it shows that NCR was thinking of postage meters as early as 1925.

The inside of the oval contains "PERMIT ' No. 5 / OFR METER / NO. 1991".
The line across the bottom contains the date, zone, weight, mail service, value figures, and an impression counter number.
The stamp appears to be from the same omni-denomination parcel post franking machine that produced stamp ESY-A15. Although the meter was never placed into use in the United States Ohmer Fare was successful in getting it placed in a post office in South Africa where it was trialed for a short time.Unlisted in 2001 edition
ESY-BK1. Continental Postage Meter Company, 1930.    [—]
In 1930 Luther Mack (founder of Mack Postograph Company) applied for a patent (approved and issued in 1935) for a limited-value postage meter. At the time Mack was probably working for the Continental Postage Meter Company which had acquired Mack Postograph in 1928. The patent illustration shows a strip of stamps that appear nearly identical to Type DB1.1 except for using "METER No" instead of "METER NO." as a prefix. Shown are three different stamp values, 2, 3, and 5 cents, plus an empty dashed square probably indicating that the machine could insert another value in that spot.
