I don't know what science teacher had all of their students do this experiment, but the coins are showing up in numbers now. See the post from yesterday. https://www.cointalk.com/threads/19...utm_campaign=Feed:+cointalk+(CoinTalk+Update)

Sure looks like it is missing to me. There is still mint luster - as far as I can tell from the photos - and that means it is not dipped in acid.

 

What do they weigh? ~ Chris

 

They look like they've been played with -

The color in the photo isn't accurate, I'm guessing.
Can you take another photo of them next to a normal
post-83 cent? We'd need to see the comparison to
gauge the accuracy of the color.

As a general rule:

If it's bright and shiny, it's been re-plated.

If it's dark, dull, and grey, it's been de-plated.

I can't tell for sure about your cent, but it doesn't
look like an original un-plated zinc cent, based on the
color and staining, etc.

 

Hi Joy, Did these unplated coins come with all the off-center struck and clipped planchet coins you recently purchased? I note that they are all 1984-D coins.
If so I think that your unplated coins are genuine and hold a greater premium than the other CP's & OCS.

 

I'm no expert like @Fred Weinberg but if you got these from the same place you got all the other cool mint errors, I would have a good feeling that they are real.

 

Just asking' for another set of photos with true color.

Take 'em next to a normal AU/UNC copper-coated zinc cent.

I haven't said they're bad, I just said the color doesn't seem right,
and I'd like a comparison photo with a normal, mostly Red, cent.

....and, I bought thousands of errors from good sources who had
access to to new coins, and used coins, and these sources many times
put in de-plated or re-plated cents in a group, thinking they were real.

 

Yes

 

I did I've bought a lot of them from the son of man that passed away

 

Getting artistic now are we?
I think that unplated is the real deal.

 

Thought yall needed a flower

 

And the son had to be 65ish I didnt ask how old his dad was, but assuming he had to be 85ish

 

There's no telling when his dad acquired these coins, I'd like to think early

 

That it very cool that you got them from a private source. Makes for the best chance that the are genuine unplated cents.

 

The two light-colored unplated cents are missing the copper layer, but they have been altered via de-plating. No Mint luster, lack of details - an easy call there.

Weighing them won't tell you anything as the plating is so slight that many unplated cents weigh the same as plated ones.

 

As for the 1985-D, it too is altered. Observe the coin Joy sent me. Notice the copper showing through the coin in front of Abe's face.

It's weight of 2.1 grams can be explained by being acid dipped, then either plated or stained to give it its color.

 

Thank you for your respected opinion about these coins.

 

Thank you so much Joe
