What do you see? (Larger photos would really help us to help you.) edit Is this the same 1960-D Lincoln that you posted on another thread? If so, only one thread is needed per question. Multiple threads leads to confusion.
I'm not an expert, but I'd guess it's the coating, and not the die itself. How ridges form is something an expert can answer though, I'm sure.
This is the first time I have posted anything about this one. They are raised edges on almost all of the letters and numbers.
It appears to be a type of machine doubling damage, if I am interpreting your red arrows correctly. Jim
Yeah, I've seen this on quite a few cents, I'm pretty sure the coating can't handle the stress when the metal gets squeezed, resulting in raised ridges on top of the higher areas ...just a guess though, and not an expert opinion.
It almost looks to me like there is either not enough pressure behind the dies to fully form these details (but enough pressure to not cause a weak strike) or maybe a planchet that is just thin enough to not have enough metal to fill in the letters / numbers? I don't know I'm just a guessing amateur.
I would agree with machine doubling some times dies loosen up or rotate a hair making what looks to be doubling but is not this is mistaken for double die a lot
I wasn't implying that this could be a doubled die. I'm already over the learning hump where everything looks like a doubled die. It doesn't look like your standard flat shelflike machine doubling which makes me think maybe if it is machine doubling the "jiggle" of the die happens when they are further apart after the strike is made? If this makes any sense. I can picture it in my head but have a hard time putting it into words.
