Philatelic Terms


Where did the word "philatelist" come from?

The word "philatelist" means a person who practices philately or stamp collecting. It comes from the French word philatelie, which was derived from the Greek words "philos", meaning loving, and "atelia", meaning exemption from tax (which also came to mean "postage is prepaid"). Philately has come to mean, specifically, the collection and study of postage stamps, postmarks and stamped envelopes and the study of postal history.

What are cachets?

A cachet is a design placed on an envelope, usually commemorating the event for which the cover, as that envelope is known, is being prepared. For first day covers, the design is usually closely related to the subject of the newly issued stamp. The cachet usually appears on the left side of the envelope.

What are stamp hinges and where can I buy them?

Stamp hinges are thin rectangular pieces of paper which are used to hold stamps in an album. One side of each hinge is coated with a special adhesive that becomes sticky when it is slightly moistened. Hinges may be purchased from stamp dealers or hobby stores. Hinges come in two varieties, flat and pre-folded.

What are coil stamps?

Coil stamps are stamps made for use in vending or affixing machines and are sold in rolls. They have perforations on two parallel sides only (either the horizontal or vertical side). The other sides of the stamps are cut straight.

What is a mint stamp?

Mint stamps are stamps that remain in their original state of issue, unused and with full gum (if so issued).

What is a joint issue?

A joint issue occurs when two countries each issue a stamp or stamps on the same date to commemorate the same subject. This happens frequently when the person or historic event honored has a special meaning for both countries. For example, on June 1, 1976, the U.S. Postal Service and the Canadian Post Office jointly issued stamps honoring Benjamin Franklin. Franklin had been the first Postmaster General of both Canada and the United States. Both stamps were designed by the same person and looked nearly identical.

What is an overprint?
overprint An overprint is any printing added to the face of a stamp after it has been manufactured. This is usually done to make stamps suitable for use not originally intended. Precanceled stamps represent one kind of overprinting. Whenever an overprint changes the value, it is called a surcharge.

Why and how are stamps watermarked?

A watermark is a special design or pattern pressed in to the soft paper during the manufacturing process. These impressions take many forms, such as letters, animals, fruit, emblems, and combinations of these and others. They are frequently hard to find under normal inspection. Watermarks help provide protection against forgery.

What is a semipostal?

A semipostal stamp frequently carries two denominations on its face often separated by a "+" and is used to pay for postage and make a charitable contribution. One denomination is the amount of postage that stamp pays for and the other, usually smaller in size than the first, is the amount that will go to support charitable organizations or help pay for health programs. The United States has issued only one semipostal stamp to support breast cancer research in 1998.

What is meant when a stamp is said to be "off-centered"?

The term "centering" refers to the stamp in relation to the perforation surrounding it. Perforations should be equal distances from the printed area. When they are, the stamp is well centered. When they are not, the stamp is off-center. A very badly centered issue may actually have the perforations intruding into the printed design. A stamp's condition and value is determined, in part, by the quality of the centering.

How can you tell if a stamp is a commemorative or a regular issue?

Regular or definitive issues are the stamps you are most likely to see on your mail. They are usually one color, relatively small and printed in large quantities to stay on sale for several years. They most often depict famous persons from history, the U.S. flag or historical artifacts. Commemorative stamps are issued in honor of an important event, person, or special subject. They are generally larger and more colorful than definitives. Commemoratives are only sold for limited periods of time. If you are in doubt about the type, consult a catalog or ask a stamp dealer.

What does "aerophilately" mean?

Aerophilately is the hobby of collecting air mail stamps, and envelopes (covers) that have been sent by air mail -- including by airplane, balloon or other types of aircraft.

History


How much did the first United States stamp cost?

The first United States stamps were issued in 1847. One featured a picture of Benjamin Franklin and cost five cents. The other featured a picture of George Washington and cost ten cents. (A U.S. Postage Rates listing is available for you to see postage rates and when they have increased.)

Why does the United States of America put only dead people on stamps when other countries picture people who are still living?

Each of the world's stamp-issuing nations has its own set of rules governing selection of subjects for stamps. The United States does not consider putting an individual on a stamp sooner than 10 years following his or her death. The exception is former Presidents of the United States, each of whom is honored with a memorial stamp on the first birthday following their death. The United States believes the impact of a person's life cannot be assessed until it has ended and that at least 10 years after death are required to make a fair evaluation. Most historians would agree that this is a sound policy.

How did stamp collecting start?

Shortly after adhesive postage stamps were introduced by Great Britain in 1840, people began collecting them. In 1841, a women even placed an advertisement in the London Times in which she requested help in collecting stamps so that she could paper a bedroom wall.

In what state was the first U.S. post office built?

The first post office was established in 1639 at the home of Richard Fairbanks in Boston, Massachusetts. The first building created to serve as a post office was built in Philadelphia, Pennsylvania in 1683.

How and why did the use of stamps get started?

The use of adhesive postage stamps, as we know them today, began in 1840 with the British postal system and was largely due to the efforts of Sir Rowland Hill. The 1840 stamps were created as a means of abolishing delivery charges based on distance and the number of pages. Weight of letters became the basis for delivery charges and stamps were used to indicate prepayment at a uniform minimum rate of one penny for a ½ ounce letter. Sir Rowland Hill believed lowering the rate would increase postal revenues through increased mail volume. History proved him correct.

In what year did the U.S. start printing stamps of different designs on one sheet?

The Christmas issue of 1964 was the first year different designs were printed on the same pane of stamps. Four different stamps featuring holly, mistletoe, poinsettia and a sprig of conifer were issued in panes of 100 stamps, each pane containing 25 blocks of the four different stamps.

Where were the first U.S. airmail stamps used?

The United States began airmail service on May 15, 1918. Special stamps were issued to indicate prepayment of mail carried on the first flights. The first route, flown by Army pilots in Army planes, linked Washington, DC and New York City via Philadelphia, PA. The rate was 24 cents an ounce. This rate included special delivery to the addressee.

What was used before stamps?

Prior to the use of stamps, the person receiving a letter paid the delivery costs. Since rates at the time were very high, many people refused to accept a letter. Thus, the post office often suffered the cost of both delivery and return of the letter. Mainly for this reason, it turned to a means of prepaying postage.

When was the first time that meter stamps were used on mail?

Meters to pay postage were first used in New Zealand in 1904. The first use in the U.S. was on December 10, 1920 at Stamford, Connecticut.

When was Zip codes first used?

The Zone Improvement Plan (ZIP) code -- a five digit number -- began on July 1, 1963. The first number designates the state or area; the next two numbers, the area within that state or area; and the last two digits, the office itself. Mr. ZIP was created to help people remember to use the ZIP code to help the Postal Service move the mail. He was printed on the margins of many U.S. stamps issued between 1964 and 1986.

Who appears most on U.S. stamps?

Since 1847, Benjamin Franklin and George Washington have appeared on more stamps than any other Americans.

In General


What makes a stamp valuable and how do you determine that value?

The value of a stamp is determined by the quantity available, the demand, and its condition. Approximate values, for both mint and used items, can be obtained from a stamp catalog.

Is it better to collect canceled or mint stamps?

This is a decision that collectors must make for themselves. Canceled stamps with light markings can make a beautiful and, of course, educational collection. They also usually are less expensive to obtain. It must be noted, however, that in general mint stamps will have a greater value in later years. This is not always true. One of the most valuable stamps, the 1 cent British Guiana, is a heavily canceled stamp.

What are the rarest or most expensive stamps?

There are more than ten stamps of which only one copy is known. And while rarity is one factor in determining value, the history behind the stamp often is more important. Some of the most famous and valuable stamps include:
  • 1 cent 1856 British Guiana (Sold for $935,000 in 1980)
  • 1d and 2d 1847 Post Office Mauritus (1d & 2d valued at $500,000 used; 1d at $1,100,000 unused)
  • Sweden 1857 3 skilling Banco Yellow (Approximately $2,000,000)
  • Hawaiian Islands 1851 2 cent Missionary ($660,000 unused; $200,000 used)
  • British Guiana 1851 2 Cent Cottonreel ($70,000 used)
  • Western Australia 1854 4d Inverted Swan ($60,000 used)
  • United States 1868 1 cent Z Grill (Sold for $935,000 in 1988)
  • Canada 1851 12 pence Victoria on Laid Paper ($80,000 unused and $50,000 used)
  • United States 1918 Inverted Jenny ($150,000 unused)

The above values are based on catalog values or last known sales.

Why isn't there just one stamp with all different prices?

If all stamps appeared the same, Postal clerks and customers would be more likely to confuse them. In fact for a period of years the Universal Postal Union required that stamps had to be a particular color based on the rate they paid.

Another important consideration is that stamps give us an opportunity to honor our great citizens, commemorate important events in our history and encourage our citizens to do things that help our society to work well, such as register to vote, and to give blood.

Why do people collect stamps?

People collect stamps for many different reasons. Some like to learn about the designs. Others enjoy them as little art works. Still others like to try to get all the stamps of one country. But most of all, stamp collectors have fun with their stamps because no collection is ever complete, so there is always a challenge. Besides, your stamps belong to YOU, and that is a nice feeling. And, of course, stamps are one way of sharing an interest with other people -- your friends, a parent or perhaps a neighbor. Even strangers can be instant friends when they discover that they both collect stamps!

How old must a stamp be before it's worth more than face value?

A stamp becomes valuable because there are fewer copies of it than there are collectors who want it. Age of the stamp is only one factor. Also important are how many were printed and how many collectors there are. There are some stamps that are 100 years old but a billion or more were printed. They will never be rare.

How and where do you get stamp catalogs, tools, and mounts?

Most often, people get stamp supplies, catalogs and stamps from stamp dealers. Visit the dealer listing on this website or look in the yellow pages of your telephone book under "stamps" or "stamps for collectors," and call before you visit to make sure that the dealer carries the things you need.

If there is no local dealer, you need to find adult collectors who can tell you where they get what they need -- usually by mail. Sometimes a member of a local stamp club (see listing on our site) will order supplies for the club members, and you can submit your order with the club order.

Why are stamps canceled?

Stamps represent money that has been paid to the Postal Service. The money that is collected from selling stamps is used to pay the expenses of transporting and delivering the mail. Once stamps have been used, the cancellation makes them into a receipt for the service that the Postal Service has given. If more service is asked for in the form of a new letter, a new stamp must be used.

Where can I put my stamps if I don't have hinges or mounts?

Without hinges or mounts it will be difficult to display your stamps in an album or on home made pages because tape or glue will damage your stamps. You could use glassine envelopes or stock cards, but stamp hinges are less expensive. Self-stick pages sold for photographs should not be used, as the stamps may be hard to remove, and when the adhesive dries, it may discolor your stamps.

If you have a design you think would make a good stamp, where do you send it for people to look at?

Stamp design ideas should be sent to:
Citizens' Stamp Advisory Committee
Stamp Development
US Postal Service
1735 North Lynn St., Rm 5013
Arlington, VA 22209-6432

Information on how new stamp designs are chosen and how to submit ideas is available on the USPS website.
