1985 D planchet error?

bigtime36

Thoughts?

It has the appearance of being struck on a tapered planchet, but that would be rare on a coin made from a copper-plated zinc planchet.

However, it is not misshapen and still retains the upset rim in the unstruck portion. I do believe it was struck on a tapered planchet. It may weigh slightly less than a regular zinc cent.

Early "Zincolns" had planchet problems, including plating and bubbling.

This one looks extreme indeed.

What is your reasoning?

One would think that a zinc cent damaged that significantly would expose some underlying zinc and cause significant lateral expansion.

the odds are even on either post mint or a error would get a expert to look it over and tell you what is is and isn't

Look at the word "Cent"

No zinc damage because it was smashed and not scraped.

If an error the letters would be strong and not mushed like in the OP.

I'll vote tapered planchet (but I won't wager money on it ).

I think the roughness in the blank areas is unstruck surface, and the mess at the lower part of CENT is the result of the metal expanding outward into thin/unsupported territory at the same time it was trying to flow into the letters.

But who knows.

I will bet money on it

Does the obverse have other areas that are affected? From the photo, looks like there is a patch affecting 'IN' and below it... and also to the left of Lincolns' shoulder?

The front has more bubbling that the photo didn't capture

I don't think it is a tapered planchet. I lean towards PMD myself. But, respectfully, if it were "smashed" shouldn't the rim be less pronounced (more smashed) and/or the coin out of round?

That would be my assumption. I don't see how the coin gets flattened like that but keeps its rim and shape.

If PMD, where did the displaced metal go? Not outward, not upward, not downward. The plating is still there so it wasn't ground away.
