Hi,
Many thanks for all your kind help.
In this topic I am going to share images of 1986 damaged penny which seems to be rare one.
As all of you know the weight of 1986 penny should be 2.5g, but in this coin you see that part the coin has been removed by any sharp thing, but its weight 2.51g? apparently this means that its weight was some thing about 3g or even may be more than that, and I believe it is rare coin!
Please let me know your opinion.
Thanking you.
With regards,
Habib.

The silver you see uncovered is zinc. It is a plated cent. Keep in mind the 2.5 gms is normal weight. I have plated cents that are 2.75 gms and while it is considered heavily plated it is still considered a normal cent.

The weight of the plating removed is very little as the plating is very thin, 8 microns. According to a previous post, all the copper on the coin would only weight about .05 grams.

Can you show an image of the edge of the coin?
It appears raised (A fake fingernail glued to the coin, perhaps?)

Hi every body,
Thank you for constructive comments and suggestions. I have to mention that a parth of this coin has been removed not coated?
The lengths, width, and depth of the removed part is 6mm, 5mm, and .09mm respectively. I am attaching image of the side of the coin.
With best regards,
Habib.

From the side view, it appears to be damage where a bit of the coin was removed. Maybe a dremel tool.

Looks like pliers were used to hold the coin. Note the 180 degree area across from the crater? You can see where the tool pierced the plating?

A tip on taking images of the edge of a coin: I use wooden clothes line pins to hold the edge of the coin. That allows me to put it under my scope to set an close up edge view. Always focus on the lowest areas before you take an image. If you focus on the highest spot, most of your image will be out of focus.

Hi,
Thank you for your opinions, but my question remained unanswered. Now, it is clear that part of this coin has been removed and its current weight is 2.51g, this means that its original weight was more than normal copper-zinc coin. Can we assume that it may was copper coin?
With regards,
Habib.

Well the zinc is showing. The coin was altered. When it was struck it didn't look like that. In fact the planchets are struck, setup and plated before it arrives as the mint. So the weight should be less than 2.5g.

But since the coins have a .1 gram tolerance, this coin could have weighed 2.6 grams when it was new, and the damage has removed .09 grams of material, 3% of the coin.

If it was copper (and the surfaces show that the coin is definitely plated something that wouldn't have occured on a copper planchet) the MINIMUM weight new would have been 2.98 grams that damage would have had to remove .47 grams of material or about 16% of the coin.

Also the surface inside the damaged area appears to be silverish colored not copper. So conclusion is it is a damaged copper plated zinc cent.

Hi every body,
Thank you very much for your complete reply.
Now I am convinced the coin is copper-zinc.
With best regards,
