Don’t know of a list like that but I do have the tolerances for CENTS

Copper cents- +-.112
Plated cents- +-.060

Hope this helps

Not an error, that part has been intentionally ground off, possibly to make a love token.
It is considered a damaged coin.

Agree that it is a counterfeit.
Another way of telling is the style of the 6
Surprised you got this at a coin show, do you know who the dealer was?

Look at the bottom of the “I” above the “M”, it has the same type of chip. There is
nothing on the Obverse like that to cause a clash. Doesn’t really matter too much

Please crop your photos to enlarge them. You are not giving us much to go on.

They are known as pocket change coins and it would be hard to find a buyer.

It is just a regular 10 cent piece. There were 142,800,000 minted.
Not rare and worth 25 cents at the most.

All 1996 5 cent coins are non magnetic, they are nickel plated copper.
Hard to evaluate condition from those photos but is only worth about $1-2.00,
why do you think it is worth more.

I wouldn’t put too much stock in that coin dealer if he can’t tell the difference between damage and an error. These have been posted more times than I can remember on various coin forums. They are easy to spot as the lettering is in reverse and concuse. If it was a genuine error, the lettering woul...

I will show you the way and let you do the searching.

Welcome to the Forum

Pictures are pretty bright to see the detail but it looks like what is called a "Vise Job"
where 3 coins have been squeesed together leaving the impressions on the middle coin.
This is just a damaged coin with no numismatic value.
