rkennedy1945 Valued Member United States 130 Posts	Posted 02/01/2023 2:19 pm Was doing my weekly rolls of half's and thought I would get an opinion on this coins surface. Also I see many types of half dollar coin surfaces and curious if anyone knows of a site that shows and explains the various coin surfaces? I see the normal, then black, gold, shiny like a proof , rough surface, etc. and never know if any are mint errors or just PMD. Response's appreciated. * Edited by Staff to Add Year / Mintmark / Denomination to Title. It's very important to have in the title. * Report this Post to the Staff
