1963-D Lincoln underweight planchet

[MintErrors]

A collector stopped by and he had a 1963-D Lincoln cent. I was able to handle it and it was easy recognized as on an extremely thin planchet.

here is what I could determine in a short period of time:

It's a 1963-D Lincoln Cent.
The coin appearance wise looks like it was struck on a planchet that may have been extremely close to a Lincoln cent planchet.
Dropping it on glass, the ring sounded like silver, BUT I have to note that this also may be due to how thin this coin is.

The coin weighs 1.89 grams.
The diameter is 21.8 mm
The thickness is 1.0 mm

I went through the 63 page PDF which lists all the majority of foreign coins struck at the US Mint.
There wasn't a good match in the 1962/ 1963 / 1964 year.

I am going to do the math to see if it is something crazy like a Lincoln cent struck on a 10 cent thickness stock.

Looks like an acid bath coin that then spent time in circulation. Not an expert on errors but that was my first thought on seeing the coin.

Yup. That's a acid coin, not a mint error.

What I thought too.

Roger that. I did tell him this at the show but he was pleasantly attempting to make it in to something else. I showed him an acid dipped nickel which was absurdly thin that was a classic with the valleys and run offs over the rim. I will call him in a few days to let him know he doesn't have anything special.

I like to convey what the owner says here, then I typically send them the link so they can read the responses. This gentleman I believe does not get on line, but the info will be passed along.
