The metal is raised next to the I in Carolina therefore it's a die crack. I can see a little doubling in other areas but it's common MD (machine Doubling). Nice to keep but worth maybe a dollar, $.25 cents for sure.
well, if thats a crack, thats the first time i ever seen a die crack skip a space...an only an uneducated noob would pay a dollar for something like that, worth 25 cents, tops....
I see the skip and I think it's possible from the shape of the coin's design that's it's possible the crack is forming from 2 directions. It could also be a crack with a extra piece of metal or a bubble of some sorts. It's not supposed to be there as that makes it interesting. A neat little error for any collection just because...so I guess I'm a uneducated noob but I'm not obsessed with these types of areas and I do have an education.
I would love to see this coin in hand or better images. The die crack could also be a die gouge for one and because of the devices and the way the coin is made it could be a doubled die. It is just hard to tell from the images but I do see shifts. I would pay a dollar just to take a look as some interesting doubled dies have been turning up and you have to be educated on them as they are a bit different with the single squeeze process being used by the mint now.
There is a recent thread which talks about how machine doubling looks on incuse design elements. You coin matches this closely - you have a bit of machine doubling. This is incredibly common, and not worth a premium.
