Each bar is minted from .999 pure copper, and clearly marked with weight and purity. They are manufactured right here in the USA by Osborne Mint - the nation's oldest private mint.

Important Features:

• Each bar contains 1 ADVP (avoirdupois) oz of .999 fine copper. This is "standard" weight rather than the "troy" weight used in gold and silver bullion.
• The Morgan design is among the most familiar (and popular) in American coinage.
• All bars are brand new and gleaming, made by the nation's oldest private mint - Osborne Coinage.
