Hi! guys, I need some help to figure out whats wrong with it. It weight 2.8grs. I'd figured it might be damaged, but have no idea what caused it. Someone tried to sand it down? If it true then how come the edge had the same thickness with a normal one. The one on the left in the picture of the rim was in question. Thanks everyone!
A caustic environment or acid is what made the striations so prominent , afterwards, the coin saw circulation to give the higher details a smoother look which enhances the overall contrast of the design. This contrast is the "details" you see
Vietguy: Take another look at the edge side-by-side.. I see your coin as slightly thinner than the control.. Make an assumption yours was slightly under weight but still within tolerence to begin with and it isn't that much of a stretch to seeing another 20 - 25 hundredths of a gram loss due to other factors.. Or an out-and-out under weight planchet right off the bat..
