Can anyone tell me what happened to these coins?

Hey, today I decided to hunt for pennies when I came across these coins specially the 1992 D Penny. The weight of the coin is 2.2 Grams. It does look like die error to me or a wrong planchet. The other coin is a 2008 which has a weight of 2.4 Grams.

They appear to be filed down to the zinc layer. Just like this one..

I don't know but it looks painful

 

Significant Abrasive damage. PMD

 

Is it really damaged? Why does it look like its spilled on top of the coin? It doesnt look like it was filed down. for example like the word One and LI in Liberty.

 

The effected area goes in between the letter B in liberty and as well as the LI

 

It's a damaged coin.

 

they are saying that it was filed down? It's hard to believe because if it was filed down. Why would it effect the area inside the letter B in Liberty? Can you please explain?

 

Without the coin in hand its very hard to say, but I'd bet the word liberty has been ground down very close to the surface of the coin and that allowed the plating inside the B to be worn away.

And another way to look at it... Explain how in the minting process this could happen to a coin.

 

Another example. You can see that this is not filed down because you can see it in the letter B in Liberty. Why Does it continue inside the letter B? To me it looks like its a coat of zinc.

Its been ground down. If you're right and its been covered in zinc by some means that still makes it a damaged coin.

 

To be an error coin , it had to occur in the mint processes...and there is no process which can do this, or there would be hundred thousands of these produced . A bored person with a hand grinder to test. IMO, Jim

 

Genuine dryer coins.

 

I really thought it was zinc coated. If you look closely in the letter B in Liberty. the effect parts goes through inside the letter B.

 

Even if it was zinc coated that's damage, not an error. As @desertgem pointed out an error occurs in the minting process. That wouldn't happen as part of the minting process.

 

The only thing I can think about the letter B is that the copper IS a coating, and as such can chip off. As far as the abrasion, look how Lincoln has lost the front of his coat...

 

Trying to copy a link. Not working.

 

These look like it was coated and not filed or grounded down
