1916 D LWC Planchet?

That's cool .It doesn't look plated ,I guess the weight might tell something.

To help rule out plating:
What does it look like by the damage on the reverse? Do you see any copper under? If the coin was plated before the damage copper should show through. I also see some brown spots on lincoln, is this something that has stuck to the coin or possibly copper showing beneath plating?

Weight will be very helpful once you get that

There was a weakness on the devices of the coin. Probably from coin circulation.

But beings that was a special year for coins, I thought I would mention it. (Not many know that happened that year)

Weight would help, but I think the chances of it being (especially from the Denver mint) anything other than a mistreated or acid etched cent is really close to zero.

While the US Mint did produce coins for a number of foreign countries in 1916, none of them match or approach the weight of this specimen and none of the coins were struck at the Denver Mint. That doesn't necessarily rule out an authentic off-metal error; there are many unexplained "orphan" off-metal errors that have emerged from the Mint. This coin would have to be submitted to a grading service for evaluation.

Science experiment,

Looks like a wire brush job to me.


It's PMD for sure.
