Yes, I know it's not a special or valuable error. We don't need to go there.
But it's different enough to immediately stand out from all the rest even at a glance.
Hey I'm always willing to put myself out there a risk "a dumb question".
So I started to think about how this happened. I'm just trying to understand it...
My understanding is that there is one collar, so it wouldn't be from for example 2 collars not quite sitting flush...
So is it something that happened during the lamination process that wasn't quite struck away in the striking process as the planchet expanded?
I notice the reeding is pretty flat, maybe from wear since the coin itself is nice and sharp in the sense that the strike seems solid and deep, even though it is heavily circulated.
Just trying to visualize how it came to be...

Looks like post-Mint damage to me. Coin got caught in some kind of roller that had an uneven surface.
PMD. Mechanical damage of some kind.
All comments reflect the opinion of the author, even when irrefutably accurate.
From the surfaces, it probably spent time in a place of slot machines (Las Vegas, Atlantic City, etc.). Maybe it got stuck in a counting machine?
I was thinking more like "placed in a bezel, then removed". Either way, it's PMD, not a mint error.

Apparently I have been awarded the DPOTD twice.
It is PMD but I am not sure what type.
I wonder if it spent too long in a dip or solution that eroded the copper faster than the nickel.
