just found this one and I’m curious if this is an error type or not. It looks like there are raised dimples on the coin, one with a crater in it. No visible indentation corresponding to the dimple on the flip side. Also, might be “missing” a chunk where the “1” of 1974 is. I don’t know how to clean it w/o damaging it, so I apologize if the dirtiness interferes with the photo appearance.
