記念切手の価値：額面より高くなるのはどれか

Are commemorative stamps worth anything?

Most are worth their face value and no more. Commemoratives are issued to be collected, so they're printed in large numbers and millions are saved in perfect condition, which is the opposite of scarcity.

That's the paradox of collecting modern issues: the stamps designed for collectors are the ones least likely to become rare. The 1993 Elvis stamp is the clearest example, with more than 500 million printed. Value comes from scarcity and demand, not from the occasion being commemorated.

What's the difference between a commemorative and a definitive?

A commemorative marks an event, person or anniversary and is printed once, for a limited period. A definitive is the everyday stamp, reprinted for years in many denominations.

Counter-intuitively, definitives more often hide the valuable varieties. They were reprinted with different perforations, watermarks and presses over long runs, which creates scarce versions. See the Washington-Franklin series for the classic case.

Which commemorative stamps are valuable?

Early issues with high face values, small print runs or famous errors. For the US that means the 1893 Columbians, 1898 Trans-Mississippi, 1901 Pan-Americans and the 1930 Graf Zeppelins.

Condition decides where in the range a copy falls. See stamp condition grades, and error stamps worth money for the inverts.

Why are modern commemoratives worth so little?

Because supply overwhelms demand. Post offices print tens of millions, collectors save whole sheets unused, and far more survive in perfect condition than there are buyers.

Unused modern commemoratives keep one solid use: they're valid postage. Sheets bought years ago can go on today's mail at their printed value, which usually beats what a dealer would pay. In the US, stamps issued since 1860 remain valid. See how to sell stamps.

What are gold-foil “commemorative” stamps worth?

Very little. Gold-foil replicas sold by mail-order and TV marketing firms are novelty items, not postage, and there's almost no collector market for them.

They're usually sold as “tributes” or “collector editions”, often in presentation folders with certificates of authenticity that authenticate nothing more than the novelty itself. The gold content is a microscopic layer, and the resale price is typically a small fraction of what was paid. The same caution applies to “collector edition” sheets from private mints.

What are Christmas stamps worth?

Almost always face value. Christmas issues are among the highest-volume stamps any post office prints, and they're saved in quantity every year.

The exceptions are the same as everywhere else: genuine errors, the earliest issues from a country's Christmas series, and unusual varieties. Christmas seals, the charity labels sold alongside stamps, are collected separately and are not valid postage.

Are commemorative first day covers and souvenir sheets worth more?

Usually not. First day covers for modern commemoratives were produced in huge numbers, and souvenir sheets tend to sell at or near face value. Both are attractive, and both are common.

Souvenir sheets and miniature sheets are issued specifically to be bought by collectors, so the same supply problem applies: almost every one printed survives in perfect condition. The exceptions are early sheets, limited overprints for exhibitions, and genuine errors.

• Modern first day covers: typically a few dollars at most, and often less than the stamps' face value.
• Souvenir sheets: around face value, with a small premium for popular topics.
• Presentation packs and year books: usually worth less than the stamps inside them.
• Worth checking: anything pre-1940, hand-painted cachets, and sheets with printing errors.
