In the context of the United States, numerous types of collectible coins exist, including patterns, which are trial coins struck to test designs and specifications before mass production. The 1975 coin patterns specifically refer to experimental issues related to the designs of various denominations, showcasing unique characteristics that make them sought after by numismatists. These coins often feature alterations in motifs or compositions, highlighting transitional periods in U.S. coinage history.
