What is a bullion issue?
Bullion issues, or rounds, are items on the fringe of numismatics. Technically, they are not coins since they are not produced for circulation and do not bear a legal-tender value. While bullion rounds are desirable to some collectors, the innate value is more often based on the spot price of the metal content on the world market, rather than the collector or numismatic value. There are many “unofficial” mints and private companies that produce various sizes and types of bullion issues and offer them for sale to the general public. The U.S. Mint currently produces bullion issues in three metals: silver, gold and platinum.
