You make a point, but my thought as to a DD, hasn't changed, still no. The 1963 is certainly a single digit doubling, but being a type VIII, tilted hub, if the 5 was doubled ( it is not), the 9 would have been also as type VIII usually are doubled towards the center or towards the edge. Show me one where the VIII doubling would produce a DD in the interior of the date only and I would reconsider. But yes that is a nice example, here is mine. Are you saying that not only is the 59 a doubled die, but it is a undiscovered DD, and a different type than the real 1959 DDO http://coppercoins.com/lincoln/diestate.php?date=1959&die_id=1959p1do001&die_state=eds ( just putting words in your mouth NK, as I don't think your are.)
Good morning. I would like to thank everyone for their input. It's a sad day here on home front. Unfortunately, it's not a DD, not a die chip or any other kind of Mint error. Before going to bed last night, a placed the coin in some warm water to see if might be something foreign that was really stuck to the date. I woke up this morning and gently patted the coin, and what do you know, whatever it was came off. It was a nice conversation piece, sure did get my blood flowing. I do want to say thank you to everyone for their help. May I say though, there are chances out there that older "undiscovered" DD may exist. If I'm correct about the 1982 DDR, only four have been found, that was in 2012. So, my thinking is, there may be undiscovered DD out there, just waiting to be found. So when someone thinks that they have one, that point shouldn't be a part of the decision making.
I'll have to look at it when I get home to see if there's any hint of possibly the piece breaking off or if was in fact a foreign substance. Unfortunately, I'm still sticking with it being foreign.
