2010 D Struck on Partially Plated Zinc Planchet Shield Cent

Here’s a rare error to come across on a zinc penny on a modern date 2010 and up.
Coins weight is 2.49 grams as copper plating adds no significant weight to change the coin at all.

Sorry, don't do facebook. Are we sure about this? Why is there copper where the zinc is? I'm just feeling a little suspicious.

 

Link goes to a bisecting die crack. Why is the rim copper color and the fields zinc on the rev and obv?

 

Link goes to the video of the coin in question not a bisecting die crack nothing raised on the obverse.

Copied that from the link given.

 

Tapping that link It takes me right to the video of this coin I am moving in my hand to show luster.
Or u might have to join the group bc it’s private. Is it showing a retained cud coin and the date is covered?

 

I get "this group is private". Shows this coin on the page,

Cool coin by the way!

 

Please. One coin at a time.

 

Join if you’re interested in the video if not all g

 

correct

 

This is the only Social media I partake in. I have zero time to get sucked into my phone. Post some more of those beauties here.

 

So Gorham, is the copper cent dipped into a solution to get it's plating? how does the process happen. I see alot of copper tones in the rim, nd when I see that I think altered.

 

Yea the rim is copper once it transitions to the field and gutter rim. And edge of coin it is zinc.
The blank goes into a copper plating bath so somehow copper won’t stick to the zinc perse and you get a partially plated penny.

 

There are some tones in the 3rd side that say dipped or altered. Tommorrow is Monday, as I have been reading up today, seems like it has been a good weekend across CT.

 

The fact that copper is peeking through on the high-relief, slightly worn portions of the obverse design indicates that the silvery metal was acquired after the coin left the press.

 

Doesn't really look like the silvery layer is plated on, but I too am having trouble figuring out why else there'd be more copper on the high points than the fields.

 

That’s my same thoughts too.
I can’t see it being plated on, and the weights 2.49 as well.
I’d think it’d add weight if plated and look different.
I “cant see” that the full copper plating is beneath all that silver area honestly.

 

The remaining copper means that the remnants of the plating weren't dissolved in the process. It is altered.

 

Plated coin.

Using either Silver nitrate or Zn + NaOH I plated many cents and handed them out at my old job

Here's one I just threw some silver on.

 

It was always less expensive to use the zinc compounds rather than the silver and it seemed to me to be easier to manipulate the design. But of course I never did such for profit, Only fun. DG
