Error Planchet | 1961-D with a very thin layer

[eaxtellcoin]

Hey Folks went to the coin show today in Centralia IL and talked to the dealers, Had a good show for 4 hrs... Very nice day.
One of the dealers handed me this coin and I just ehhh?
It's a weakly struck OBV and REV 1961-D. Was barely able to read. The dia is about a dime diameter, weighs 1.2G
and appears to be only a small copper layer. Any idea's for him what this could be? Thanks all! hopefully he joins the forum!

Might be a split planchet. Was it "weak" on both sides? If so, it's probably a split-before-strike.

Yes Sean Both sides very weak - and was missing rim. Like I said about the diameter of a dime..
I looked at the link - not quite.

Acid dipped?
Does it have a funny texture?

[GrumpyEd]

They're dipped in acid as experiments or to shrink them to dime size to spend in old vending machines.

These look dime sized and thinner than cents at 10x the surface will look like an orange peel but most wording is still clear.

This one is a 1941 toned and probably made long ago next to a regular cent, some have less texture:

I agree. Acid dipping removes the rims, narrowing the diameter. A split planchet doesn't reduce the size. Acid dipping does.

[eaxtellcoin]

No - does not have a rough surface at all. Just very weakly struck...

[coop]

The surface don;t always look rough.

Does it show metal flow lines around the outside devices? You should be able to tell if the coin was struck on a thin planchet versus some sort of damage by the metal flow.
