I have seen plenty of thin planchets, but they are all missing details significantly. This one has a strong obverse strike, and a decent reverse strike. It also is a bit smaller in diameter and weighs only .7 grams. I am positive it is altered, but how are the details so strong for it being so thin? I checked the edge and it definitely is not 2 shaved coins stuck to each other, and it is copper. Anyone have any idea about this?
