A 1922 silver dollar can also be worth more if it has any special markings or mint errors. For example, 1922 silver dollars that were minted at the Philadelphia Mint have a "P" mint mark on the reverse, while those minted at the Denver Mint have a "D" mint mark. Silver dollars from the Philadelphia Mint are generally more common and less valuable than those from the Denver Mint.
In addition, there are a number of different varieties of 1922 silver dollar, each with its own unique characteristics. Some of these varieties are quite rare and can be worth a lot of money to collectors. For example, the 1922 "Double Eagle" is a rare variety that features a double-headed eagle on the obverse. This coin is worth significantly more than a regular 1922 silver dollar, so it is important to be aware of its identifying characteristics.
If you have a 1922 silver dollar, it is important to have it appraised by a professional coin dealer to determine its value. A coin dealer can assess the coin's condition, rarity, and any special markings or mint errors that may affect its value.
