Missing clad layer on Quarter

Probably not the real deal. Just need some expertise on this coin just in case. I wouldn't like the fact if I tossed it back in the wild and it was an error. thanks in advance.

No, it's been copper plated.
It is not a 'missing outer clad layer' error.
It's worth face value - it did not leave the US Mint like that.....sorry

Thank you Fred
I don't think it's plated. I think it's just rusty.
rust is iron oxide
I am surprised you think this quarter has been plated.
Looks like simple corrosion to me.
Environmental damage. Not plated.
I don't agree - if it were environmentally damaged
surfaces, then all the outer clad layers would have
to be missing, right, for it to be copper on both sides.
Clad coinage doesn't 'rust' like that.
There is way too much detail for us to be looking at
a copper core - and I'd bet that the coin weighs close
to a normal clad quarter - probably a touch over.
It is not corroded or surface damage only, imo.
Can we get an edge view, and a weight, in grams or grains?

Looks like a low tide mud coin to me. Stained by the elements.
If you're right and everyone else is wrong you sir are truly a giant genius and gentleman.
I'm just giving my opinion - I'm not a genius.
I'm just saying that in my view, the coin is just
not simply 'corroded' from being buried or just
having enviornmentally damaged surfaces.
Viewing the photos, I believe the coin was copper
plated - what happened to it after it was copper
plated could be other surface damage.
As mentioned in my previous post, I'm guessing
that the coin weighs the normal clad quarter weight,
or a touch more for the plating. I'm also guessing
that the edge of the coin is also all copper colored.
Hey, if I'm wrong I'm wrong.......but that's what it looks
like to me..

I agree with likely metal detector find. I’ve dug clad coins many times that have that orange brown discoloration.
If there's one thing I've learned here, it's to keep your silly azzed comments to yourself. So I'm not even gonna say what I was thinking, about it looking like it was found in a septic tank and all...
Metal detector coin
I don't think the clad layers are corroded and missing, I think they are just rusty. I've seen clad coins rust like that before. It's red rust over a normal quarter to my eye.
Like this only less green:
I recall reading that the color change on 75Cu25Ni alloy ground find/metal detector is due to a Cu enrichment of the surface.
NOTE: I do not have the references.
I think the acidic ground conditions cause the Ni to leach from the surface leaving localized areas of higher Cu concentrations. The Cu then reacts to form the brown oxides and/or other compounds.
I'm relying on memory but feel this is reasonably accurate. If anybody has data/info to support or correct this, I would be very interested in seeing it. Thanks
Also, I don't like referring to this discoloration as rust. I guess you can call any oxidized surface rust, but when most people hear the term, they associate it with iron oxide. I suppose iron oxides can form on a coin if the ground conditions are right, but I feel that the discoloration is primarily due to corrosion of the metals in the alloy, not accreting iron oxide.
Yes, technically rust is oxidized iron. But it is much easier to understand "rusty" rather than "chemically oxidized" for most people. IMHO
Agree. I generally use the terms environmental corrosion or environmental damage to describe this type of discoloration. IMO, it conveys the information without implying Iron oxide, and there are possibly other some metallic reaction products (sulfides, carbonates, etc) besides oxides.
Do you have any info to help support that the discoloration is caused by Copper surface enrichment due to Ni leaching? I remember reading that a few times on the various forums from people that I felt had credible chemistry/metallurgy backgrounds, but hate repeating it as "fact" without some confirmation.
Too many words for the average idiot. Just say "magic".
However, here amongst people who are supposedly a little more in tune with coins, I'd err on the side of being accurate.

No, I don't.
I have read all the inputs here and gone back over them.. including scrutiny of the pictures. I also have dug quarters with a similar appearance. After studying the picture in the OP, looking at other inputs (notably @Oldhoopster - which I can support from my own observations), I have come back to Fred's opinion of copper plating. The quarter just does not have the 'in ground' look I have often seen... the color is very uniform (would like to see the edges), not like soil corrosion. So I will vote with Fred on this one. Cheers, RickO
Copper plated nickel?
Sorry Its back to the bank.
. If it was worth more than face value I probably would of kept it. Note the edge was the same color around the whole quarter.
I seen many quarters from the ground also didnt look the same to me. JMO
Car wash change.
You sure its not chocolate?
