Hey Everyone,
I recently found this quarter and it jumped out at me because of the copper strip across the reverse. The coin weighs 5.63g which is ever so slightly lighter than average but still within the mint's tolerance. It could have been missing clad before the strip was rolled which would account for the normal weight and the even strike.

That said, the main thing causing me a little hesitation is that the missing clad doesn't impact the rim which seems both odd and unlikely to occur naturally.

Thoughts?

First thought is residue of some type, which might come off in a pure acetone bath. Otherwise, I'm stumped.

@crh, that is kinda interesting. I agree with @half that this isn't a strip of copper showing through since it doesn't extend into the rims and there are small areas where the color is coming back to grey. You could confirm by checking the coin's weight as it would be low if a strip of that size was missing.

Looks like a stain not missing clad.

I think John1 is correct. It's a stain. Regards.

If there was a lamination strip, there should be some evidence of a sharp edge.
20x or more magnification should provide a definitive answer, but from what I see on my 24 inch computer monitor, I have to agree with above comments.

It looks like maybe the nickel layer had a gap in it, which when the layers were bonded together let the copper layer squeezed into the gap. I think Coop has some pictures of strips. The weight would be the same because no material is missing.

I lean toward a stain of some sort, however it came to be there.

Thanks for all the quick responses! I've tried using 100% acetone and it has no impact on the strip. No fading, no color pulled off, etc. So if it is a stain it's not impacted by acetone.

@Cujohn the scenario you mentioned is the exact same one I was thinking about as a possibility for how it could be an actual mint error. That's why the biggest hang-up to the theory in my mind is that clad isn't missing from the rims. I would expect clad to be missing the whole way across, including the rims if that's how it was produced.

So I don't think it's a stain but I also am not sure how this could be produced at the mint.

Another interesting curiosity.

I agree with Cujohn.
The upturning mill putting on the protorim might have caused the cladding to overlap the copper strip.

Can you get a closeup image of those areas of the rim?

Of course, I'm more than happy to provide additional images! I think this is about as magnified as I'll be able to get:

It might be a missing cladding or carefully removed? Note the area that color is weaker on just that area. So it made have fell off post strike or was removed? But it seems odd that the rim is still the normal color?

Pete, that's what I was thinking on the upsetting mill pushed the nickel over the copper .

Thanks for those extra images but you included images of the rim, not the edge. Maybe I should have said reeds.
The reeds are from the "Third" die used in striking coins.

Yepper Cujohn, I had a feeling that's where you were coming from. Hard to know for sure but hopefully an image of the reeds in this area might help.

Is not missing clad by Mint production errors. I see remaining clad everywhere. This it is humans made simulation of the missing clad.

Sorry just an DAMAGE coin.
