Anyone have an idea what this coin is? I found it on the beach in Delaware close to the area of a 1700's british ship wreck. seems to be bronze, but not positive about that. It is extremely worn and very thin. It looks like it has letters PFENNING on one side with lion standing facing. IAD under the lion and looks like EEOH on the other side of the lion. flip side is a bust facing right. Only letters that I can make out are REX. It is about 16mm in dia. I have found some coins that are British on the net that are close but not the same.
