Req 3 — Stamp Terms in Action

This page is your stamp collector’s vocabulary lab. You are not just memorizing words — you are learning to look at a stamp or envelope and notice the clues that collectors use to describe it correctly.

Bring real examples whenever you can. A real stamp, envelope, booklet pane, or piece of metered mail is much stronger than a definition spoken from memory.

Requirement 3a

A perforated stamp has small holes punched between stamps so they can be separated neatly. An imperforate stamp was issued without those holes. Early stamps were often cut apart with scissors, so seeing whether a stamp has perforations is one of the fastest ways to classify it.

Look at the stamp’s edges. Tiny even holes usually mean perforated. Smooth cut edges all the way around usually mean imperforate.

Requirement 3b

A mint stamp has never been postally used. If it still has original gum on the back with no hinge disturbance, collectors may call it mint never hinged (MNH). A used stamp has been canceled or otherwise shows postal use.

This difference matters because mint and used examples often have different values and appeal to different collectors. Some collectors prefer the fresh look of mint stamps. Others like used stamps because the cancellation proves real postal service.

Requirement 3c

A sheet stamp comes from a large flat sheet sold in panes. A booklet stamp is cut and packaged in a booklet or folded pane for convenience. A coil stamp comes in a long roll, often used in vending machines or by businesses that mail a lot.

You can often tell them apart by the way the edges are perforated, by spacing, or by attached margin paper. Coil stamps especially may have straight edges on opposite sides because of how they were trimmed from the roll.

Requirement 3d

Collectors pay attention to numbers and markings printed in the margin around stamps. A plate block includes part of the sheet margin with the plate number that identifies the printing plate. Booklets, coils, and other formats may have counting numbers, position numbers, or markings that help identify how the stamp was produced.

These details are useful because they prove where on the sheet the stamp came from and sometimes separate a common example from a more interesting one.

Requirement 3e

An overprint is extra text or a symbol printed on a stamp after the original design was made. A surcharge is an overprint that changes the stamp’s value. Postal services use overprints for new governments, special purposes, emergencies, or rate changes.

If you show an example, point out what was added later. The added printing is the clue, not the original stamp design underneath.

Requirement 3f

Metered mail uses a postage meter imprint instead of an adhesive stamp. Businesses, schools, and offices often use it for large amounts of outgoing mail. The printed mark shows postage paid, and it may include a town, date, slogan, or permit information.

This is a good example to collect from everyday envelopes at home because metered mail still appears regularly in business correspondence.

Requirement 3g

These four categories tell you what job a stamp was made to do.

• Definitive stamps are everyday workhorse stamps, usually printed in large numbers and used for common postal rates over long periods.
• Commemorative stamps honor a person, event, place, or anniversary and are usually issued for a shorter time.
• Semipostal stamps include extra value beyond postage to support a cause.
• Airmail stamps were issued specifically for mail carried by air.

If you show examples, explain what features helped you sort them into these categories. The picture, printed value, wording, and issue purpose all give hints.

Requirement 3h

A cancellation is the mark that prevents a stamp from being reused. A postmark usually includes the place and date where the item entered the mail. Sometimes the two are part of the same marking, but collectors still talk about their different purposes.

If you have a used stamp on cover, point out where the date and location appear and where the stamp was canceled.

Requirement 3i

A first day cover is an envelope bearing a stamp canceled on the stamp’s first official day of sale. Many first day covers also include a cachet related to the stamp’s theme. Collectors like them because they tie together the stamp, the envelope, the cancellation, and the event.

The envelope itself is part of the collectible, so keep it flat and protected.

Requirement 3j

Postal stationery is mail material with postage already printed or embossed into it. An aerogramme is a lightweight folded letter sheet for airmail. A stamped envelope is an envelope with a stamp design already on it. A postal card is like a postcard with postage already included.

These items remind you that collectors do not study only loose stamps. They also study the many forms mail can take.

You can now speak the language of stamp collecting. Next, you will learn how collectors judge value and condition instead of guessing.
