I found this coin on a roll hunt and it has a lot of different toning along with a rainbow following the rim. However, I am curious if there is a way to tell if someone did this with chemicals/heat or if the toning came by a more "legitimate" process. Posted pics below.
(Also, side note: the bank told me that due to the coin shortage vendors are starting to use half dollars in place of quarters, and I can no longer order half dollars boxes for now. Anyone who roll hunts halfs run into this too?)
