2011 d roosie partial clad missing??

Is this a partial clad missing error? Or environmental? Should it weigh less? Value?

Might be a coffee stain variety...only reason I say this is because you can see the clad under the discoloration on S in STATES making me believe it is just a stain. Then again I have no expertise in this stuff JMO.

If there's a ridge around the brown area about the thickness of heavy duty aluminum foil it's partial clad.

It looks like enviromental from the picture.

Yep. Looks like some environmental damage/stain. Usually from what I've see on genuine errors, the copper is more one-colored and there is a more distict edge where the surface layer is missing. I also don't think I've see an error like this that was completely isolated, not connecting to the rim (not to say that it can't happen).

what if....


what if the clad layer is just really thin to non-existent there ??

The clad layers are rolled between two heavy steel rollers to bo reduceded to the proper
thickness. If there's a hole in the strip it will still be about the same thickness as the rolls
are set adjacent to the hole. There should be a discernable ridge. The end of a strip may
have a tapered ridge but even it should be discernable.

It has a definate ridge.

There's also a chance it's etched with acid.

If the ridge exists at the top along the rim this is the likely cause.

Sorry, it's not an error.

if it was created with acid, wouldnt the detail in the copper be mushy?

Copper is more resistant to some acids than cu/ ni.

Based on what I can see in the
scans only, I'd say it's NOT a
partial clad layer missing error.

While I tend to agree the thing presents a sort of enigma for me. There's no doubt something
that would preferentially attack the cu/ ni but I don't know what it is. There is something seemingly
going on under the D of United. I wonder if there's any apparent separation between the I and the N?
It would be nice to see it in hand in any case.

There's little doubt it's damage but it lies a little outside my experience.

fred, i would be willing to send it to you to examine. send me a pm if you are insterested.
