This is a pure copper replica modeled after a coin! I am selling it to organize my collection. How about it for those looking for copper coins? Design: One side features a bald eagle and the words "Strength, Freedom, Pride," while the other side is fully engraved with the American flag, embodying the core elements of the American spirit. Weight: 1 avoirdupois ounce (avdp ounce) = approximately 28.35 grams Comes with a clear case (see photo 3) Size comparison with a 500 yen coin in photo 4
