Collectible coins from the United States, particularly those minted in Philadelphia, can include a variety of types such as trial coins and patterns from specific years like 1868. Trial coins are experimental pieces created to test new designs, sizes, or compositions, often not intended for circulation. Patterns are similar, serving as prototypes for future coinage, and often feature unique or modified designs that may never have been produced for general release. These coins are highly sought after by collectors due to their rarity and historical significance.
