The focus here is on pinpointing the cessation of the production of United States quarters composed of a 90% silver alloy. These coins, historically a significant part of American currency, contained a substantial amount of precious metal.
The significance of this change relates to the intrinsic value of the coins. Silver’s fluctuating market price meant these quarters held a melt value potentially higher than their face value. This influenced collecting habits and investment strategies, as individuals sought to acquire and hold these pre-1965 coins.
