Collectible coins encompass a wide range of types, including historical, commemorative, and trial coins. The United States has produced numerous collectible coins, with specific subsets such as trial coins, which are experimental pieces created to test designs, weights, or minting processes. An example is the 1885 trial coins, which were produced to evaluate striking techniques and are highly sought after by collectors due to their rarity and historical significance. Other varied patterns, differing from standard coinage, can also include unique designs and errors that add to their collectible value.
