I know it's not silver as I can see the copper core but when dropped it has that familiar sound. It weighs 5.092 +/- grams. Just not sure about the oddity. Could it just be as simple as a thin planchette? Enlighten me please and thank you as always!
@DJD, the tolerance was about 0.2 g on these http://goccf.com/t/251134#2113155) and with this amount of wear, I think that it might have still been intolerance as minted. Hard to say now though I agree.
