Collectible coins encompass a wide range of numismatic items sought after by enthusiasts and investors. In the context of the United States, notable examples include the 1 One Dollar coin, issued in various designs such as the Peace and Morgan dollars, which hold significant historical value. Buffalo Nickels, minted from 1913 to 1938, are particularly valued for their distinctive design featuring a Native American on the obverse and a bison on the reverse. Both types offer insight into American history and craftsmanship, contributing to their desirability among collectors.
