I’m trying to understand annealing errors and how to recognize them. In hand the coin on the left has a more “pinkish” hue the a straight copper color. I also do not see any abrasive lines, and no silver showing anywhere. It is pretty evenly colored all over. I would appreciate your insights
You'd need Fred to take a look if it's been circulated a while. The one I found the edge was "clean clean" while front and back weren't. I have no idea how to identify them if they've been circulated a while and toning from circulation. An edge picture is useful also. Below I still don't know if it's an annealing error or some dried liquid or something like that that was on the coin at the mint. It came out of a whole box of 2019 P AMP quarters and the only one like it in the box the rest were BU. Looking online, the graded ones all look like different patterns on the faces and different levels of improperly annealing, so I don't think that's a good way to identify it just from the obverse and reverse.
here's another thread that's a bit more recent of someone on this forum and a discussion about it. https://www.cointalk.com/threads/salt-river-improperly-annealed.366662/ my opinion though, a view of the edge of the coin would be helpful. take a best guess with a few opinions, but in the end, I think you'd need to send it in for a professional attribution and slabbing to 100% confirm it. most of the graded ones on Ebay sell for $30-$40 so i'm not sure it's worth it really to find out with certainty.
Here is a picture of the edge. The coin in question is in the middle. So I guess I have to conclude toning.
John and Sal......Thanks for the input. @John Burgess John.....your info was especially helpful I appreciate the time and effort. I think I understand now after reading the linked thread and a little googleing.l
