The coinage in question, issued by the United States Mint from 1948 to 1963, contained 90% fine silver and 10% copper. The specific metallic composition and weight resulted in a measurable quantity of the precious metal within each coin. This intrinsic metal value distinguishes them from clad coinage introduced later.
The inherent worth based on silver has made these coins attractive to collectors, investors, and those interested in precious metal recovery. Their historical significance as a circulating form of currency during a time when silver was a standard component of U.S. coinage also contributes to their desirability. The value fluctuates according to prevailing silver market prices.
