A small letter or symbol found on a 1921 Morgan silver dollar denotes the location where it was produced. These marks, if present, are typically located on the reverse of the coin, beneath the wreath. The absence of a mark indicates that the coin was struck at the Philadelphia Mint. Coins with a “D” were minted in Denver, while those with an “S” originated from the San Francisco Mint. These identifiers are crucial for identifying the origin of the coin.
These location indicators significantly influence a coin’s value and collectibility. Certain mints produced fewer coins, making those examples rarer and more sought after by numismatists. The historical context of each mintincluding its production volume and any unique characteristics imparted to its coins adds another layer of significance. Understanding the relationship between the mint and the number of coins produced, and the mint mark, allows for a more accurate assessment of its potential value.
