Did you know I was the one that coined the phrase "Cool Beans!"?

Really? I have been saying cool beans for years! That is awesome.
But back to topic... Any idea what actually causes this? I mean, the coin community figures out most of the fakes eventually. I can't imagine one person etching away and putting in circulation across the country. So what is the cause of these zincolns doing this?

This one was altered chemically after being minted. Read back a few posts and I think you'll agree.

No doubt. The one I found was altered or simply PMD. I guess my question is why are so many of these showing up?

I have found 2009 Copper cents that show a similar color on them. It really looks like Zinc showing through, but since they aren't plated, it can't be Zinc.
I'm not sure what is doing it but I don't remember ever finding an older Copper Lincoln that showed it. Maybe some new treatment at the mint is causing them to tone this color.

Aren't all zinc planchets Plated? I don't really understand the plating process (or the clad process for that matter) and how they are different. Seems to me silver plate can see the plating wear off? So why not copper wearing off of zinc?

I know these are stupid questions, but I really don't mind sounding stupid...maybe I will learn something!


Okay - Cladding is the bonding together of 2 different metals. Plating is where a surface covering is deposited on a conductive metal. HA!

Yes, the Zinc planchets are plated.
In 2009 the mint produced some Copper cents for collectors. These were put into mint and Proof sets only. The 2009 business strikes are Copper plated Zinc. In all there were 20 different varieties of Lincoln cents produced in 2009: http://www.lincolncentsonline.com/2...20Cents.html
A similar situation took place in 1982 when the mint produced both Copper and Zinc cents, that year there were 8 different varieties including the Proof.

I don't know if this will be helpful or not, but here is an example of a partial plating error (notice the dark gray line in between the plated and non-plated areas):

Here's another coin I have that you can clearly see that the copper has been worn off exposing the metal underneath. Some how a chemical washed or deteriorated the copper. Which is another weird coin that I can see fitting in PMD. The coins that myself, coinhuntingdrew, fromms2244, cwb, all have very similar attributes. But have been located on different year coins and areas around the country. And some of the pennies were found among fresh rolls too. Those partial plating pics look to me like a chemical rubbed over the penny leaving a burn mark, hence the dark line.

First impression is that one looks like it was mounted in something. Why, I have no clue. Let's see what others think

Probably sanded to remove the plating. It may have been a Dryer Coin? (note how the rims are covering part of the edge devices.

Early zlincoln Dryer Coin. I can see that now. Funny how it didn't blister or otherwise damage the center plating
