The presence of a small letter or symbol on a 1922 Peace dollar indicates the location where the coin was struck. These marks are typically found on the reverse of the coin, near the word “ONE.” Common examples include “D” for Denver and “S” for San Francisco. Coins lacking such a mark were produced in Philadelphia.
The marks are crucial in determining the value and rarity of these silver dollars. Production figures varied significantly between mints, leading to differing levels of scarcity for specific examples. Understanding which facility produced the coin helps collectors assess its potential worth and historical significance within the context of early 20th-century American coinage.
