The things that have me puzzled about this coin are the obverse rims. The rim to the NE and the opposite rim to the SW both are folded inward toward the center of the coin. If the damage occurred from a single blow to the coin the rim damage would be in one direction. Also the damage to the devices seems to be worn in ...almost polished. Seems to have happened over a period of time. Maybe not in a dryer, but it appears to me like it has been stuck in some sort of moving machinery of some sort.
