Collectible coins encompass a wide range of types, including historical, commemorative, and trial coins. Trial coins, such as those minted in 1872 in Philadelphia, were experimental pieces created to test new designs or minting techniques. These coins often feature unique patterns that distinguish them from regular issue coins, making them highly sought after by collectors. The collectibility often depends on rarity, condition, and historical significance.
