Hi, I'm new to this forum. Hope this is the right place to post. I have a 1965 solid copper quarter , full thickness and does not appear to be plated. It been circulated and there is some wear on George's hair so it does appear to be solid copper. I'd like to get it authenticated and appraised. Also, if it is what it appears to be what would anyone's guess be as to it's value ( other than "a pretty penny") Mow let's see if I can upload some pics !   |

It looks to be either plated or painted that color. What is the weight of the quarter in grams?

Copper plating is pretty easy to do at home.

 to the forums, sycon! If you drop it flat on a table or countertop (not on its edge!), does it sound the same as any other quarter? |

Definitely not painted !
I've had it for 35 years. It has darkened over the years and appears quite a bit darker than the photos show.
I weighted it on my crude scale at 5.625g . I also got about the same for a normal quarter.
It's VERY hard to tell but it does appear to have a slightly different (lower fq) sound.
I did take it to a coin dealer about 25 years ago and he said that it was copper but was only worth about $12.00. He did not impress me as especially knowledgeable however.

It seems odd to me that it is missing both the obverse and reverse clad layers. If it was struck on a copper cent planchet wouldn't the strike be weak? And the weight would be that of a cent 2.5g. If I had to make a guess I would say that it's copper plated out side of the US mint.IMHO, I am not a pro. John1  P.S. Did the US mint make any foreign copper coins for some other country that year?

If it was actually missing both clad layers the weight would be closer to 4 grams.

Nickel and Copper are very close in density, so weight doesn't help distinguish between solid copper and plated--all else being equal. Conversely, if a planchet was struck from stock that somehow wasn't properly clad, but of the correct thickness--it would weigh the same as normal. Just thinking aloud here--I'm unsure how this could be verified non-destructively.

Take a pair of snips to it :) You'll quickly find out if it's full copper.

What about running a current through it, would a full copper conduct x-+ amount of electricity than a regular Washington quarter. Or a water test might help, actually DVcollector says their about the same density so that wouldn't work. IDK looks nice though. Good Luck |

The coin doesn't seem to have any luster or wear. It should have one or the other. I had a quarter that was missing the obverse clad layer and the copper, although Brown, still had almost full luster. I also had a Dime with the obverse clad layer missing, but it was Red/Brown. The color on the OP's coin doen't look even. I'm attaching a photos of both of my coins to compare the color and luster. Do you have a photo taken strait above the coin? I really hope it is all copper, because I love new error types, but the look seems wrong.   ANA ID: 3203813 - CONECA ID: N-5637 Clean a coin that may be worth collecting? Please DON'T! When in doubt, leave it dirty!!

read this-your quarter should 4.7 grams if it is really missing the layer. That 4.7 gram figure is for a coin missing ONE layer, the OP coin claims to be missing both layers so as I said closer to 4 grams. Quote:
Conversely, if a planchet was struck from stock that somehow wasn't properly clad, but of the correct thickness--it would weigh the same as normal. Correct but where would such a planchet come from? I'm sure the mint would notice a coil of solid copper strip labeled as quarter stock when they went to put it into the blanking press. Of course they could put cent strip into the quarter blanking press but then once again the blanks would be light weight. I would try a metal detector. They work by the use of a tuned circuit. The coil puts out a magnetic field which, when distorted by a metal object, results in a change in frequency in the tuned circuit. Copper is now resistive to the passage of a magnetic field than nickel is and therefor distorts the coil field more. (A thin copper plating on a regular clad coin should not significantly alter the signal of a clad quarter, but a solid copper coin should be noticeably different. |

Or arc welders brazing torch.  And oh one more thing Since you weiged it at approximately 5.625G and a normal, no wear clad quarter should be 5.67G, that to me would indicate a plated quarter. Since yours has wear it should really have been less than mormal wieght. If it was missing one layer would be 4.7G and much less if missing both layers. Now if it was Gold plated it would make up for the wear since Gold is heavier. If so, at the present price of Gold, your rich. Otherwise you have a coin that has been played with and is still worth $0.25 approximately. Edited by just carl

My metal detector shows me what coin is buried. It shows Dollar, Half, Quarter, Dime, Nickel, Cent and Zinc Cent. It may show the denomination of a gold piece, but I've never had a hit on one. I wonder what reading it would give on a copper Quarter. I sold the Quarter above, or I would test it to see what the detector thought it was.
