Dearborn Moderator United States 97162 Posts	Posted 10/30/2022 1:49 pm nasty bit of work, that zinc rot is. It seems to show up near the date and MM most often - possibly due to split plating exposing the zinc when the cent was young and fresh. Collecting since 1972.

Wiquiocho Valued Member United States 72 Posts	Posted 10/30/2022 6:39 pm I see. I have begun searching through a stash of older coins that I have been collecting for the past the 30 years or so. So I imagine the quality of these coins wouldn't be that great. But I am still hopeful and eager to find that "one" coin. Zinc rot has now become my new nemesis in my journey #128545;.and to my allies full of knowledge and wisdom I must humbly thank you all yet again for your skillful eyes and information.
