Collectible coins encompass various types, including patterns, trial coins, and regular circulation issues. In the United States, trial coins, particularly notable from minting processes, were often struck to test designs or minting techniques. The 1837 trial coins from the Philadelphia Mint are examples of such pieces, showcasing the early efforts to refine coinage in the U.S. They hold significant value for their historical importance and uniqueness within numismatic collections.
