The composition of United States quarters minted in 1964 consisted of 90% silver and 10% copper. This metallic makeup contributed significantly to the coin’s intrinsic value beyond its face value, particularly in later years as the price of silver increased. The presence of a substantial amount of the precious metal distinguishes these specific coins from subsequent issues.
This characteristic made these coins a popular form of small-scale silver investment and a collectible item. Their historical context is also noteworthy, representing a transition period in U.S. coinage. Prior to 1965, circulating silver coinage was common; however, rising silver prices led to the removal of silver from dimes and quarters and a reduction in the silver content of half dollars.
