year.
Certain dates are much more collectible than ordinary modern pennies.
2. Look for the mint mark.
Depending on the coin and year, a small D or S, or the absence of a mint mark, can be significant.
3. Examine the lettering.
Look closely at words such as “LIBERTY,” “IN GOD WE TRUST,” and “AMERICA.” Doubling or unusual spacing can sometimes indicate a valuable variety.
4. Pay attention to unusual errors.
Off-center strikes, doubled designs, wrong-planchet errors, and other genuine mint mistakes can attract collectors.
5. Don’t clean the coin.
