My roll of 2022 quarters that has a few pieces with some folded rim fins also had this quarter in it. I don't know much about coins or errors but thought this might be considered annealing? Bottom quarter is just for reference of "regular" piece.
Thank you for the note. This helps me understand why the first time I saw the quarter the stained area was obviously darker than the rest of the quarter but the next day in different light I may not have noticed anything if I hadnt already seen it look darker the night before. Is staining like this common, personally I think looks kinda cool.
