Spence Moderator United States 34442 Posts	Posted 06/01/2023 06:06 am Hard to say what exactly has caused this surface discoloration, but I would assume that it comes from something that happened to this coin after it left the mint. For example, this coin may have spent some time in a water fountain.

Dearborn Moderator United States 98209 Posts	Posted 06/01/2023 08:26 am Yep, this coin has spent time in a water feature for a long time before getting rescued and getting placed back into circulation.
