Before diving into this, how was this coin acquired--in circulation as change, found in a roll, other?

Never seen anything like this. Any chance you can get the diameter or compare it to another cent?

Add after strike. The fifth photo show the rim is OK, and the material do not show the really structure of the core coin.

Nice artisanal work.

I don't think that really matters but it does weigh 2.5 grams

My first thought was applied solder, but I'm surprised no one else mentioned this... where was it found again?

I bought it seller hasn't gotten back to me on that. But most likely a roll and was circulated for a bit.

I've also talked to a few very reputable friends the have been dealing with errors for years and years and a very knowledgeable(Steve and Robert)
I'm open to everyone's opinions too.
I've seen stiff collar errors finned rims that are major like this (ofc they are vertical) and the inside rim is still present if that's the case in my coin.
Stiff collar errors are somewhat difficult to understand.

WOW, gorham. You go in big assertion. WOW.

Maybe your friend deal with errors, I do not question this. BUT, do I know from mid 80's it is impossible to have this from the Mint? And more then anything, do you know that the core of your coin could not be bend more then 48 deg without structural broke?, and do you know that in the modern mint process this kind could happened only in other part of the mint building when they calibrate the collars and this part of the building do not have passage to the production line?.

Do you know that the collar stiff in normal strike occur only in the case of "off center"?

And also look at your cooper plated coin parts, will show you many thing which contradicted this theorem.

Do not feel bad with my answer, far from me to offence. Please make some check on zinc alloy and his reaction to the vertical forces. You will understand. Sorry I will not do a class of the material resistance and physicals proprieties under applied forces here..

I have never seen a fin form in both directions towards the obverse AND reverse, AND be that thick AND still weigh the proper amount.
Tanman2001 posed a question here that so far went unanswered as to the diameter of this coin.

@Dear, Also the gr. must be high. This year is impossible to go like this. No way for this year the collar to deform or such. We discuss about B-Ball press where if a coin do not fit all the line stop. Look at the color of the metal on silver tone is, never you will see a zinc with this bright and color.

I'll take what u say into consideration you stated I a lot of didn't know silviosi. I've seen you comment on others paints and usually you are right.
I've never heard about that breakage at a certain angle before

The diameter thing I'm not able to measure it so idk about that.

Going from the on the bottom left from k5 to almost k9 on the obverse though the whole regular rim is there but then the rim is connected and smooth with the extra metal and it flows all together. How could that be and to me that would be bc of it all being one as the rims putter edge that's just me.
I'll take a closer look with a loupe again tm and thinking about your comment as well.

I've messenged Jason Cuvelier. I've emailed mike before but couldn't find his email or it anywhere for some where reason. I'd be happy to email him idk how to dm here. I just need his email.
The coin is the same diameter as other shield cents the thickness of it tho when comparing the edge of coin is thicker to be expected in this situation maybe by half more I'm not sure.

If you send the coin to PCGS or NGC Mike or Fred or such mountains experts will give the observation. Some times such coins finish in my lab for metallurgical forensic and analyses. Hope will be OK for you, Good Luck.
