JohnWayne007 Pillar of the Community Canada 1188 Posts	Posted 11/24/2019 11:45 pm I finally fixed my lighting issue on my microscope and while I was looking at some pennies I came across this one, looks like there is a 7 under/beside the 7's but I'm not too sure. I do know these come out of the coin kind of like a hump so I don't think it is PMD.

spru Bedrock of the Community United States 12477 Posts	Posted 11/25/2019 12:49 am I see what looks to be a sort of ridge between the sevens, but it doesn't follow the curve. Could it be some form of Die Deterioration?

JohnWayne007 Pillar of the Community Canada 1188 Posts	Posted 11/25/2019 02:22 am I took a few more pictures, looks like the same thing for both 7's there looks to be another ridge after the last one.

merclover Bedrock of the Community United States 10635 Posts	Posted 11/25/2019 02:39 am I think you're correct, not PMD. Spruett is right, the ghost doesn't seem to follow the flow of the 7, so I'm guessing not Machine Doubling, so I too vote on some sort of Die Deterioration. This is one for the experts.

JohnWayne007 Pillar of the Community Canada 1188 Posts	Posted 11/25/2019 03:30 am i managed to get a really good shot of the last 7 and I don't know but it looks doubled in the pic to me. Of course I could be wrong. Something is going on here one way or another. Edit* If you look you can see it looks like there is another 7 directly underneath the last 7.

Coinfrog Bedrock of the Community United States 94367 Posts	Posted 11/25/2019 08:49 am Bit of did deterioration doubling? Report this Post to the Staff
JohnWayne007 Pillar of the Community Canada 1188 Posts	Posted 11/25/2019 12:50 pm Im not too sure, I wasn't aware that DDD could form a separate, second distinctive number. The stem of the last 7 (on most 77's) is not as curved and is straighter than the 1st, the last 7 in this looks like its sitting right on top of another 7, notches and all witch I've never seen notches on a MD or DDD before so this would be a first for me. if you look at the last 7 under the front of it closer to the first 7 there is another notch tucked in there as well. The pictures get a bit clearer if you click on them and blow them up a bit.
