I found this today looking through my nickels. I wish it was in better shape, but still a cool find! Feel free to share yours if you have one.
At one time I used to go through boxes of nickels looking for things of collecting value. I think I must have gone through 200 boxes. Anyway I found one of these and possibly two. I say possibly two because the other one I found the date was almost completely gone but I could tell from the way it was doubled it had to be 1939. A book on minting errors for nickels says there are 2 versions of the 1939 doubled die with one being worth more than the other one but I think the one you and I found are the more valuable ones.
There are TONs of things to look at. D/horizontal D’s, DDRs, Henning Nickels, etc. Never too late to start looking now!
That’s a beauty! I think I’ll add mine to my next ICG submission. I think I’ll keep a small collection of slabbed error coins I found. I’ll now go back through and check for the reverse of 38.
