The query addresses the terminal date for the production of United States quarters composed of 90% silver. These coins, often referred to as “silver quarters,” held significant intrinsic value due to their precious metal content.
The historical context is important as these coins represented a tangible link to an era when circulating coinage contained a substantial amount of silver. Their replacement with clad coinage (typically copper-nickel layered over a copper core) marked a significant shift in U.S. monetary policy. Consequently, the scarcity of extant silver quarters adds to their collectible value and historical significance.
