The metallic composition of United States coinage has varied considerably throughout history. The quantity of the precious metal contained within specific denominations, particularly silver, is a defining characteristic influencing their intrinsic value and collectibility. For instance, certain dimes, quarters, and half-dollars minted before 1965 possessed a 90% purity, resulting in a substantial metallic content.
The presence, or absence, of silver within older coinage significantly impacts its worth beyond face value. Coins with a high percentage of the precious metal are often sought after by investors and numismatists due to the inherent value of the metal itself, as well as their historical significance. This inherent worth provides a hedge against economic fluctuations and offers a tangible asset with lasting appeal. Historical context, such as the Coinage Act of 1965 which largely eliminated silver from circulating coinage, further amplifies the demand for these older, more precious specimens.
