Coverage

PlainCoin covers ordinary business-strike (circulation) coins in three series. A date and mint mark must be on the list below; we never guess an issue that wasn’t made.

Not covered

• Proofs, special mint sets and special finishes. A possible special finish gets no ordinary-coin conclusion.
• San Francisco cents and dimes, including business strikes.
• Wheat cents, Shield cents, nickels, half dollars, dollars, post-1964 quarters, bullion and foreign coins.
• Altered or counterfeit coins. Photos cannot authenticate a coin.

“No mint mark” means none is visible. It never implies Philadelphia by inference alone. From 1965 to 1967, US coins carried no mint marks at all.
