Can anyone explain how this happened? I saw someone say before there is no way you could have a real double headed coin? Though of course it is a mirror image, not true double head. Anyone want to spend $85k for it? http://cgi.ebay.com/Unique-Genuine-...4088856QQcmdZViewItemQQptZCoins_US_Individual
It's an in-collar, first-strike brockage of the obverse design on the reverse face. A nickel remained behind in the striking chamber and another planchet was fed in on top of it. The two were struck together in the same collar. These are extremely rare in nickels.
I think the guy never expects to get it, he's either showing off or hoping to get off ebay offers so he doesn't have to pay the fees.
Wouldn't that cause the reverse to be imprinted (force into the metal) that appears to be raised. Ice
Yes it would be incuse, and it is on the coin in question. The fact that it appears raised is an optical illusion.
