MintedNotPrinted Pillar of the Community United States 1510 Posts	Posted Today 10H 10M ago The flip was helpfully labelled "quarter" The weight is proper, so it's not missing a layer or plated over and heavy. The coin's surface has the appearance of a naturally toned copper coin, red brown to purples. The edge has no seam. Science experiment or truly an error? Thanks for looking.

MintedNotPrinted Pillar of the Community United States 1510 Posts	Posted Today 9H 51M ago It truly doesn't appear plated. Edit: Here's a closeup and coin scope shots: Edited edit: I don't mean to be obtuse, I'm not convinced it's a true error. Old toned-over copper plating perhaps explains the look, but it would have to have been an extremely thin and uniform plating.

MintedNotPrinted Pillar of the Community United States 1510 Posts	Posted Today 1H 50M ago Thanks, NumisRob I started to lean that way thinking more about the reeding, it would still have a seam on an annealing error, I think. Report this Post to the Staff
