I have a 1957-D double die on the date. I've seen many with 1 or 2 numbers being doubled but not all 4 like this one. Is this a known double die and do you know what it may be worth?
I've got a couple 57-D's that look like yours, their neat looking,but thats about it. Mark it Machine Doubling and put it in with your collection and compare other coins to it. A learning piece...
Thanks for the info. I thought it might have a little more value being it was spread evenly through all 4 numbers.
