Collectible coins encompass a wide range of numismatic items, including specific issues such as the United States one cent penny. Patterns and trial coins, like those produced in 1960 by the Philadelphia Mint, are experimental pieces created to test new designs or processes before mass production. These items are often sought after by collectors due to their rarity and historical significance. The unique attributes of trial coins distinguish them from regular mint issues, making them valuable in the collectible market.
