Greenstang Posted May 16 Share Posted May 16 (edited) Looks like environmental corrosion, possibly from being buried. In the future, please show both sides and crop and rotate your photos. We don’t need all of that background. Don’t know why so many Newbies post photos upside down or sideways, they wouldn’t hang a picture on the wall that way.

Coinbuf Posted May 16 Share Posted May 16 Without any further information and photos of the rev and the edge the best guess is simple environmental staining, as greenstang noted it may have been buried in the ground. In the future if you want help you need to help us by providing good cropped in focus photos of all three sides of the coin, obv, rev, edge. In addition the weight (to two decimal places), diameter, and thickness may be needed to give you a correct answer. In the case of this coin there are a couple of real mint errors that can look like this but without a weight and the proper photos we cannot be sure.
