So do the forum members. Such as, what coin is it? (i.e. What denomination?) Coin of the US or some foreign country?
What info are you looking for? Best anyone here can tell, it's a 1980 coin. If you want more than that, you're going to have to give more than that.
I assume this is what you're thinking.... http://www.lincolncentresource.com/doubledies/1980ddo1.html
It certainly looks like a doubled die to me. The 1980-P is a tough one to come by as well. Nice find!
Take a look at the link I posted earlier. While it certainly would be nice to see the entire coin, nothing I see even remotely suggests it is anything other than the linked variety.
Here's another link. Awesome find! I found one a few months ago roll searching. http://www.coppercoins.com/lincoln/diestate.php?date=1980&die_id=1980p1do001&die_state=mds
The top photo is from http://doubleddie.com/828697.html showing the 1980 DDO-001 The bottom coin is the original poster's coin. It IS a match.
