Hello folks, I was recently goin through my friends collection of Wheat back pennies when found a very interesting coin. It's a 1919 Lincoln Wheat Back. Under the 1919 date, between the first 1 and 9, is another 1 and 9. It's not visible with the naked eye. I discovered this under 10x-20x magnification. So would this be an error? If so how many are know to exist?
Too worn to see anything. Could of been a Die Deterioration Doubling issue which is caused by a worn die strike. Considered worthless doubling. Nothing major.
