@paddyman98. In the October 21st issue of Coin World, John a. Wexler's article did show a 2019 Lincoln cent with a Doubled Ear (the lower part of the ear lobe) but the photo of the OP's coin looks nothing like it.
you obviously did not look at the pics. in pic 133 you can see the outline of the whole ear lobe even of the die gouge in the lowest part of the earlobe look again bro it all there I know its almost too good to be true but I hope you find one as well happy hunting
If you read my reply you'll see I did not comment on whether your coin was a Doubled Ear or not. Read it again. I said it looked nothing like the 2019 Lincoln cent pictured in John A. Wexler's article in Coin World magazine. Buy the magazine and see the photo for yourself. And it would help if you answered @paddyman98's question. Who confirmed it? Despite your seeming to not understand my first reply, I do hope you really have a Doubled Ear coin.
Perhaps confirming your "confirmed DDO" with an actual expert at any TPGS will give you the true answer. Your coin has already been "un-confirmed" here by error specialist/collectors. So, it is "questionable at least". Surely you wouldn't want to attempt to sell it as such w/o being absolutely sure it's an authentic error, correct ?
Sorry, but your coin doesn't look like the Wexler's 2019-D DDO-001. Since the doubling is to the die, all of the DDO-001 will look the same. "Sorta Close" isn't good enough. Were you referring to A 2019-D being a confirmed DDO (which is true), or are you saying YOUR 2019-D was confirmed (if so, by whom).
Looks like the ear took a hit. The metal is pushed up front bottom to top in pic 132. In pic 138 Abe looks like the victim of the dreaded Black Spot Disease.
Picture #137 looks like a contact mark to me. The ear took the main force of the coin contact and it pushed up a bump on the other side of the ear. Reed
I do not ~ IMO~!! think any single squeeze "DD" are really such as they just had a single press of the die, so any jiggling or studdering of the computer controlled engraver or wiggle of the blank die in the process is mechanical doubling as it is when it occurs with multi-squeeze coins and should be in the separate DD category IX, "Only God Knows", and not called doubled dies. Jim I do not intend to irritate believers, just point of view.
