Lets make this a learning experience with a process of elimination.
1st item on the poll:
1. Why can't it be die polishing?
Note the area affected by the anomoly. The fields are what are polished. The area affected is the rim area. (There is die polishing on the center of the die and even some clash marks, but we are examining the rim area)
2. What is the purpose of die polishing?
Die polishing is used to remove clash marks.
3. What areas are usually polished on a die?
Just the areas affected by the clashing. Polishing removes some devices that are mid, so they only want to remove the clash marks.
The area in question is a rim issue and not a center die issue.

Next poll item: Die Deterioration: What do you see on a die that is wearing? There is Die Deterioration in areas affecting the devices. But the area next to rim would still be strong normally with a normal strike.What areas are affected? The areas affected by Die Deterioration are the devices facing the rims first. Then the die flow is noted toward the rims on the field areas. But this cuts off at the edge of the die.Why is this rim not affected by Die Deterioration? The normal strike would help roll the rim higher toward the edge of the coin marking the rim rounded. On this coin this is not present. So it would not be a Die Deterioration issue.So the rim area question is not answered yet.Edited by coop

Machine Doubling 2% 1 Votes Ejection doubling 5% 2 Votes The area in question is not affected by Machine Doubling or ejection doubling. This only affects the devices, not the area of the rim.

Coin damage 7% 3 Votes
There is a little coin damage on the rim on image 01 by the date area. But the overall view of the rim area is not affected by coin damage.
So what are we missing on this coin?

The outside rim is normal.

I'd like to change my answer to 'something else'.  |

Question: Was it a single cause or a combination of two or more?

Single cause. Ready for this?
Tapered (rolled thin) planchet.
The top of the head is slightly thinner and reverse on ONE CENT. The bottom of the bust and STATES has the rim formed in this area. Had me going for a while, but thought I would take you through the detective work.

Thanks guys. I find something that stumps me for a time and I post it. I like to make things educational rather than give a yes or no answer.
