Collectible coins encompass a wide range of items, including historical, commemorative, and trial coins. In the United States, the 5-cent nickel and half dime are notable examples, with the nickel introduced in 1866 as a replacement for the half dime. Trial coins, such as patterns from 1882, were experimental pieces struck to test new designs or compositions before full-scale production. These coins can hold significant value for collectors, particularly if they are rare or feature unique characteristics.
