It seems that I have found a quarter that was struck entirely in copper. Both sides of the coin are copper colored and there is no line on the edge of the coin. Does anyone know if this might be worth something more than $.25?
It is more likely a quarter that had been in water or has other environmental damage. In order to be a copper quarter the outside layers would have to been missed when the blank was made. It then would be real thin and weigh a lot less than 5.67 grams of a normal quarter. Cleaning it would damage it more, for it is damage in the first place.
It appears that you have a plainchant error and not a minting error. The plainchant was supposed to have a nickel over coating and somehow got through the production process and the minting process undetected. If it can be certified then you would have something of value to an error collector. Take the coin to a dealer and see what he or she says.
Before you get too excited ,check to see if it was plated. there are copper coated quarters that are errors from the mint .these bring big money . If the clad layer peeled away from one side or the other ,then it is worth a lot of money . if the quarter was left in the annealing drum too long it gets coated with a copper color dust - also worth money ,but not as much . I forgot to mention that the seam on the edge of the coin worries me .I am leaning towards a Plated coin . Go to an unbiased collector in a local coin club to get a professional opinion . DON`T go to a dealer ,as he will tell you it is not worth anything ,then offer to buy it .
It is possible that your quarter could have been cooper coated by another coin. This is done if a copper coin and a silver-looking metal are sitting in a harsh chemical, such as liquid toilet cleanser. The cooper particles come loose and settle on the other metals, giving the other coin a copper glaze. Or it could be what the other guy said. Either way, do take it to a coin dealer. You do have an interesting find.
