What is this?

Just gonna post this one, let's have a conversation about the authentic ones and altered examples.
I am just into my pile of pocket change, I have it sorted and this one pops up.
It did get a soak in distilled water for about an hour.

Something called Bullseye plating.. I think

 

It's a zilincoln after all the mints best abomination yet still a cent for now.

 

Wait so an actual error?thought this was just one of the thousands of plating anomalys for zinc cents.

 

I saw this look on some 2012D's except the zinc was showing around the letters of the perimeter and full copper in the center. I have been searching for that roll for a few years now.

 

Here's the thread. https://www.cointalk.com/threads/check-out-these-two-partial-plated-cents-very-strange.338300/

 

We'll let you go on this one.

 

Sounds like defective copper plating around the perimeter for a couple like that
If we r even talking about the same thing haha prob not but hey conversation right

 

Missing clad on the perimeter, is usually a stretching of the copper plate., as the strike stretches the planchet into the collar.

 

Those are wild, hadn't seen that thread.

 

Yes they are.

 

So what did you find today.

 

Note the top of last 'T' of trust and the 'ER' in America. Good sign of thin plating at time of strike.

 

I did my best Alurid with trying to get the in hand look,
most of the perimeter devices shows some split plating.

 

Looks like someone used a torch lighter and burned the center plating off dropped in cold water then spent some time in circulation.

 

That would be tricky. Copper melts at 1984 F; zinc boils at 1665 F. I found this out when I was focusing sunlight through a large lens onto a Zincoln (because Science!); the coin popped, with a wisp of vapor coming out.

 

Wouldn't the fact that the copper plating on these is so thin that it wouldn't take as much heat to burn off and or displace the copper to expose the zinc, I'm not a scientist so if you say it's not possible then I'm inclined to believe you but just saying from past experiments I have done myself that the result of a torch lighter made it look really similar to the one in this post.

 

Yeah, you could oxidize the copper without disturbing the zinc underneath. It would still be tricky, though, because once the zinc is exposed it oxidizes a lot more easily than the copper. Basically, almost anything that will attack copper is even hungrier for zinc.

 

I looked for Bullseye Plating and most of the articles I found were primarily discussing toning issues (artificial vs natural). Couldn't locate an error listed as Bullseye Plating. Maybe someone with a more in-depth search engine will prevail.
I found an Unplated Zinc Cents article:
https://conecaonline.org/unplated-lincolns/
and another quoting @Fred Weinberg:
https://markedmoney.tech/2019-cent-partial-plating-error/
and a very old one from Mike Diamond:

I am not sure this is real or not. One thing that it has going for it is Mint Luster in the zinc areas. The zinc is the same color as the split plating around the perimeter.
And one other thing, It doesn't show small specs of copper plating under magnification.

I also see that when these show up here on CT that they are rarely given the go ahead as a partial plated cent.

I am not fully sure, what I have here, it doesn't look like a reverse electrolysis cent.
