Certain United States coinage contains a percentage of silver. The cutoff dates for these precious metal inclusions vary depending on the denomination. For example, dimes, quarters, and half dollars minted in 1964 and earlier are composed of 90% silver, whereas some silver dollars contain 90% silver and were minted until 1935.
Identifying coinage based on its constituent metal composition is significant for collectors and investors. Historical context contributes to value; coins from eras with higher silver content are often sought after due to their intrinsic worth and collectibility. These older, higher-silver content coins represent a tangible asset class that can appreciate in value.
