1940 Lincoln Cent... Off-metal error ??? Foreign planchet ???

robkool

I recently went through a roll of wheat cents, and found this unusual looking coin. Doesn't look like your average chocolate brown wheatie, but more of a brass-like composition. I know most wheat cents should weigh about 3.1 grams, but this one blew away the scales at 3.3 grams. It even makes a different ping sound different from others.
Opinions ??? Perhaps struck from some foreign planchet ??? All comments welcomed. Thanks !!!

Very interesting. Kagin's had a 1940 cent certified by ANACS as struck on a brass planchet in the case at the Santa Clara show this weekend.

This might be similar?

Looks normal to me

Based on your scale's weight,
it's almost 51 grains.

Normal is 48, with a 2 grain tolerance.

It's not struck on a foreign planchet;
it might be on a rolled thick planchet.

These are scarce, but not rare items,
and in circulated condition, tend to
bring $50-$100 retail, IF you can find
the customer for it.

Thanks for your input Fred...
It's an interesting analogy about the rolled thick planchet, but this cent is of the same thickness like the rest. The coin just feels more dense, & heavier.
The weight came out to be 51 grains...

Mass spec or specific gravity. If you can't do it, go to the local university chem lab. The first is non-destructive and will give surface metal composition, the second more of a PIA and need to take in a "normal" for control ( I would recommend for both tests, and see if you can see the published standard for one cent piece).
