I've had this Morgan sitting in a drawer for the last couple of years. When I pulled it out, I noticed that the 2x2 it was in had a small tear, and that the coin had some ugly yellow toning in that area, around the 'RTY' in LIBERTY on the obverse. I don't usually see this on coins that are just exposed to air, so it may be caused by the broken plastic. Has this happened to anyone else?
