Spence Moderator United States 34453 Posts	Posted 07/14/2025 06:42 am @bjs, the mint wouldn't test individual flans for hardness, nor would they test after minting. Rather they would hypothetically test the die for hardness. However, see here: https://www.error-ref.com/?s=hardness+test Quote: No unambiguous examples of Rockwell test-marked dies are known among U.S. coins.
