Collectible coins encompass a wide range of numismatic items, including coins that are issued for circulation, commemorative coins, and patterns or trial coins. In the United States, the 25-cent quarter is a popular collectible, with the first official quarter dollar minted in 1796. Pattern coins, such as those from 1840, were created in limited quantities to test new designs or compositions before official release. These trial coins often hold significant value among collectors, particularly those produced at the Philadelphia Mint, which is known for its historical significance and production quality.
