Collectible coins encompass a wide range of categories, including historical coins, commemorative issues, and specialty items like trial coins. The United States has produced various trial coins, which serve as experimental pieces intended to test design or production processes before full-scale minting. In 1976, to commemorate the bicentennial of American independence, special coin designs were released, including the iconic 1776-1976 quarters, half dollars, and dollar coins. These items are sought after by collectors for their unique historical significance and limited availability.
