Found this cut reale and can't ID it. It is very thin (1.1MM)and weighs 1.3gms. I thought it was very worn but then the detail is still good. Calculating the coin diameter from the 1/4 peice I come up with about 26 to 27MM. Also it would make the coin weight at about 5.2 gms. I can't find any design like this in my KP book. Any ideas?
