The Standing Liberty Quarter was minted by the United States from 1916 to 1930. The 1920 issue, particularly from the San Francisco Mint (marked with an "S"), is sought after by collectors for its historical significance and design. The coin features Lady Liberty on the obverse and an eagle on the reverse. The San Francisco Mint's production was lower compared to other mints, making these quarters more valuable in the collectible market. Condition, rarity, and mint marks greatly influence the value of the 1920 Standing Liberty Quarters.
