Collectible coins encompass a wide range of items, including various denominations and types produced for circulation, commemorative purposes, or as art pieces. So Called Half Dollars are a category of medals that were often issued to commemorate significant events, individuals, or anniversaries, typically featuring a design akin to a half dollar coin. Heraldic Art Medals, on the other hand, showcase artistic representations of heraldry or symbols and can be considered collectibles in their own right. The year 1948 is notable for various coin types and commemoratives released by the United States, which may appeal to collectors due to their historical significance or rarity. Unknown varieties may refer to coins or medals whose origin, purpose, or design details are not well-documented or recognized within the numismatic community.
