TNG Bedrock of the Community United States 10284 Posts	Posted 03/03/2020 10:33 am I'm going to say that they are the same planchets but the ones used for proofs were polished BEFORE they were struck in the way proof coins are struck. The proofs are struck under a higher pressure and the striking is not done at the faster speed that circulating coins are minted. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 03/03/2020 12:39 pm Also the fields are polished making them very shiny. On some coins now they are reversing the polishing design on proof coins on the Silver eagle proofs from West Point: The 2020 ones are not enhanced, the 2019 has the option: Normal 2020 proof reverse Edited by coop 03/03/2020 2:05 pm Report this Post to the Staff
