Req 4 — Catalogs and Condition

These two parts teach a lesson that every collector learns sooner or later: a stamp’s value is never just one number. You need a catalog to identify what you have, and you need careful observation to judge its condition.

Requirement 4a

A standard catalog helps you identify a stamp and gives a reference value. The Scott catalog is one common example in the United States. A listing can tell you the country, issue date, denomination, color, printing method, catalog number, and separate values for mint and used examples.

How to use a catalog

Start with the country that issued the stamp. Then compare your stamp’s design to the illustrations or descriptions in the catalog. If more than one listing seems possible, look for the clues the pamphlet points out: perforations, color, paper, or watermark.

On many catalog pages, you will also see information about printing method and listing style. That matters because two stamps that look almost alike may still be different issues.

The catalog value is a useful guide, but it is not the same as the price you will always pay. The pamphlet explains that catalog value is a retail figure reflecting recent selling prices, supply and demand, and market conditions. Common stamps often sell for less than catalog value.

Here are a few reasons catalog value and purchase price can differ:

• The stamp may have faults such as thin spots, tears, missing perforations, or hinge damage.
• The market may be full of common copies, which pushes prices down.
• A dealer may price material differently based on demand, location, or how quickly they want to sell it.
• The exact stamp may not match the higher-value listing if the perforations, paper, or watermark are different.

Requirement 4b

In stamp collecting, condition means the physical quality of the stamp. Condition is one of the biggest factors in value. Two copies of the same stamp can be worth very different amounts if one is clean and well centered and the other is damaged.

The pamphlet separates grade from condition. Grade is about centering: how evenly the design sits inside the margins. Condition includes other physical traits such as gum, tears, creases, pinholes, color quality, and missing perforations.

Things to inspect

• Centering: Is the design evenly placed, or does it crowd one side?
• Perforations: Are they complete, or are some missing or cut into the design?
• Gum: On a mint stamp, is the original gum intact, regummed, lightly hinged, or heavily hinged?
• Surface and paper: Look for tears, thin spots, creases, stains, or pinholes.
• Color and freshness: A faded or toned stamp usually has less appeal than a bright, clean one.

The pamphlet lists terms like original gum, regummed, no gum, never hinged, lightly hinged, and heavily hinged. Those details matter because collectors often pay more for cleaner, less disturbed examples.

Once you can use a catalog and judge condition, you are ready for the tools that help collectors handle stamps safely and identify fine details.
