Role of Mint Marks
Mint marks are small letters on U.S. coins that indicate the minting location. They play a significant role in determining a coin’s rarity and value.
- P: Philadelphia
- D: Denver
- S: San Francisco
The 1975 No-S Proof Roosevelt Dime is exceptional because it lacks the “S” mint mark, which is standard for proof coins produced at the San Francisco Mint.
