The worth of a 1921 silver dollar is not fixed. Its monetary assessment is subject to several variables, primarily its condition, mint mark (or lack thereof), and prevailing market demand. A coin in circulated condition, exhibiting wear and tear, will generally be valued closer to its silver content. However, an uncirculated example, retaining its original luster and showing no signs of handling, commands a significantly higher price.
The historical context of this particular coin is significant. The 1921 Peace dollar marked the beginning of a new design commemorating peace after World War I. The Morgan dollar was also minted in 1921, making it a transition year. The relative abundance of these coins, especially those from the Philadelphia Mint, means that many examples are available to collectors, affecting their overall valuation. However, examples with specific mint marks or notable characteristics can be substantially more valuable.
