Design creep??? Really?? That is definitely interesting, however, I do not recognize that term.... Cheers, RickO
Interesting. From what I understand this anomaly happens when a "soft die" that was not properly stress hardened begins to expand in the press.
I've not heard of this before reading this post.
This proves that it is never too late to learn stuff.

Happens when the lady running a press has her nail file slip while examining a nickel.
Are you saying that that is the entire reverse?
I have not seen one in hand. I have seen a few over the last year or so on the net. At least one TPG certifies the error.
I believe the design has expanded outward making it larger than normal.

Actually at least two TPGS's slab these. The person who discovered the error sent a group to ICG. He had sold some on Ebay and was trying to find out what they were. I contacted the mint to discover the specific terminology they used for this error. "Design Creep" was already in the marketplace so we stuck with it on our label. The submitter graciously gave me one of these coins for my teaching set.
PS The OP's coin shows this characteristic better than most I've seen.
I had missed this.
So the outer circumference of the die was abraded away by the collar as the die went up and down in it?
I like your explanation as that makes sense.
What was the mint's explanation and what was their name for the effect we see?
"Design creep" reminds me of Dr. Frank-N-Furter or maybe an MC Escher staircase.
I did not know this even existed.

I've had this happen to some extent on dies that I did not harden sufficiently.
I found that if the lower die in the coin press was "spreading" it would soon jam in the collar. I don't think that the up-and-down motion of the die inside the collar would result in the perimeter of the die being shaved off. The underside of the collar hole is beveled and there is no sharp edge there to shave metal.
If the upper die was spreading, it could do this without getting stuck in the collar. The collar floats on air pistons and if the upper die became too large to fit inside the collar, the die would simply push the collar down with each strike. The result would be a coin with the appearance of being struck in a collar, and a normal strike on the lower side, but a spread design on the upper side.
What is the exact diameter of the coin shown at the top of this thread ?
If it jams in the collar, what does the strike look like?
If fully struck, does the coin look like a partial collar?
The seller just listed a new lot of 5. I might snag one.
What is the typical die life for modern nickels? Anyone know?
edit: Would a die problem such as this shorten the life of the die?

It's kind of cool.
I am not sure I was aware of this before.
I think I may have noticed a few of these and tossed them in my ever-growing pile that I call my "2nd look" jar.
(Which I don't ever get around to looking through........)
