This page is a supplement to my "G is for G stamp" page, where you can see the "A" thru "G" non-denominated rate-change stamps. But the alphabet stamps are not the only ones the USPS has issued without denominations - there have been thirty-some other ordinary First Class rate stamps, several semi- postals, special stamps for Bulk Rate and other high-volume uses, and four lettered Official stamps. Below are the vital statistics about all of them I know of up through July 3, 2020. I am providing images so that if you find some of these in a drawer and want to know what they are worth, you will be able to identify them.

NOTE that I do NOT include the FOREVER stamps, as these are always valid for the current one-ounce first-class postage rate, so that's all you need to know.

1/2/21 - The current value of a FOREVER stamp is 55¢

The first section below lists ALL non-denominated stamps, regardless of type - standard definitives, semi-postals, bulk rate and other precancels, or Officials. Immediately below that I show all the USPS postal stationery - postal cards and emvelopes. And below that section I have created separate sections where I repeat the special types such as precancels and officials.

Every stamp shown below is still valid as postage, with the face value given here,
BUT some of them have restrictions - the ones on which I note "PRECANCEL" require a special permit,
and the ones noted "OFFICIAL" can be used only by government agencies.

It looks like the USPS has abandoned the idea of new rate change stamps. Back in 2007 they issued the Forever Stamp (the Liberty Bell), and stipulated that it will ALWAYS be valid for the one-ounce First Class rate. When first issued, it was worth 41¢; Then it went to 42¢, and as of May of 2009 it was worth 44¢. And when rates go up again, it will assume the new rate. So they don't need rate change stamps any more. Alas, I liked the postal alphabet, and was looking forward to the rest, and the images they would select.

I have not tried to show here all the varieties of each stamp. The white- background G stamps, for instance, occur with the G in red, blue, and black. All have the same value, 32¢. Similar variations occur for some of the others. The color of the background is the key - and the letter on the stamp, of course - find the one that looks most like your stamp, and you'll have its value.

It is no coincidence that so many of the ordinary First Class non- denominated stamps are Christmas issues, since those have to be planned and printed well in advance, and any hoped-for rate change within a few months before or after Christmas cannot be finalized long enough ahead to be sure the denomination on the stamps will be correct - the first two of these, in 1975, were intended as rate change stamps, but the new rate (13¢) did not go into effect until Dec 31, so they were issued at the old rate, ten cents. The next two were part of the change from 18¢ to 20¢, and were issued with the "C" stamp. The 1991 issues were intended to be issued at the time of an increase from 29¢ to 30¢, but the USPS lost its appeal for that rate change, and they were released at the old rate, 29¢; and the 1995 Love stamp had to be printed before the new rate that went into effect in December of 1994 had been approved, so it was issued with just the date, to make it available for Valentine's Day.

Note that, while most of these stamps were designated initially as valid for domestic use only (and some are inscribed "Domestic" or "For U.S. addresses only"), the USPS Domestic Mail Manual states explicitly that all non-denominated stamps are valid on international mail, except for those with special service inscriptions. See: http://pe.usps.com/text/imm/immc1_005.html.

152.2.d. Nondenominated postage stamps (except for those that bear uniquely domestic markings, such as First-Class Presort, Bulk Rate, Presorted Standard, or Nonprofit Organization) may be affixed to postal items that are sent to foreign countries. The value of such stamps is linked to either a current or a former domestic rate (e.g., the "H" stamp has a postage value of $0.33). Since the international postage rates are always higher than the comparable domestic postage rates, mailers who affix a single nondenominated postage stamp to their outbound mailpieces must add additional postage to comply with the international rate schedule. Note: The nondenominated Breast Cancer Research semipostal stamp, which has a postage value that is equivalent to the domestic rate for a 1-ounce letter, may be used for international mailing purposes.
