Major Types of U.S. Stamps

There are many types and sub-types of US issued stamps. Although most people think of a stamp as evidence of prepayment for mail. These are many other types of stamps which are produced as evidence of prepayment of fees for a number of purposes. This is just a list of some of the more common that you may encounter. This is a very brief list of them and an explanation of their intended use. A more robust list is available.

See the list of stamp categories, stamp formats, perforation types and cancellations for additional information.

The first two are the most common stamps types and are used for normal U.S. Postage.

Definitive's (A.K.A. Regular)
This is the normal postage stamp. The workhorse of the lineup if you will. This type has been around throughout postal history. Use for franking everyday mail, it’s issued in a variety of denominations for general use. These are generally issued for a long period of time.

Regular issues present some interesting challenges to the collector. They are reprinted several times due to their long term use so the chance of a difference, error or other variant may appear. Color changes, printing type, sizes and details due to different printers, printing methods, plates, worn plates or even variations in materials such as inks, gum, watermarks or paper may be found.

Commemoratives
Commemoratives have been issued in the United States since 1893. These are issued to commemorate or honor a specific person, place or event. They are generally printed in smaller quantities and for a shorter duration than regular issues. Usually on sale for a few months to a year at most and are generally limited to a few denominations such as the standard USPS First Class letter rate.

The first U.S. commemoratives were produced for the World’s Columbian Exposition and the 16-stamp series depicts the various stages of Columbus’ voyages.

Commemorative

There are a couple categories that are mentioned in articles and catalogs but it's not a "purpose" type. They are somewhat subjective and determined by the collecting community.

U.S. Classics
Many stamp collectors consider U.S. stamps released prior to 194? to be "classics".
The Scott's U.S. Classic Catalog spans 1840-1940.
The US Classic Society - Their Web site does not state a specific date range but seems to stop with the large bank notes of the 1870's - 1880's

Miniature works of art.
While many collectors consider all stamps as miniature works of art some only consider certain classic stamps and or engraved designs to be "miniature works of art". Art, like beauty is in the eye of the beholder.

Back of the Book Stamps (BoB)
The following types are often referred to as “back of the book” stamps. This is a reference to the fact that they are listed in the back half of the Scott's U.S. Specialized Catalogue. This is not an all inclusive list.

Semi-Postal's (Charity Stamps)
Semi-postal's are a relatively new addition to the stamp types offered by the U.S. They carry an addition charge or premium which is intended to raise cash for a specific charity or cause such as Breast Cancer Research.

Airmail
In 1918, Airmail postage has been available since 1918 Service was started in the U.S. and the need was there for an Airmail Stamp to prepay airmail postal rates. Although mail is routinely carried by air now, airmail stamps are still issued as there are still a few countries that differentiate Air Mail services. From 1934-36, the Postal Service issued Airmail Special Delivery Stamps. These were to provide air postage and a fee for the special delivery.

Postage Due

Parcel Post
In 1912, stamps were introduced to pre-pay postage on parcels. Parcel Post Stamps were issued in twelve denominations, and had the same look, format and color. So much so that Postal workers had trouble telling the difference between the 1¢ and $1 stamps. In 1913, parcel post charges could be paid for with any stamp, and Parcel Post Stamps became obsolete.
