The following description is from www.coinsite.com:
Lamination Error: A coin with a fragment of metal missing or peeled off the coin's surface. Caused by dirt or gas trapped in the strip as it is rolled out to the prescribed thickness. Lamination errors may be missing or attached to the coin's surface. In the case of clad coins, the outer layer may be completely or partially missing on one or both sides.
It depends on what you mean by copper. If the coin weighs as much as and is as thick as a normal quarter, what you have is probably a plated coin from a high-school chemistry experiment (I know, I used to do that!). In this case it is considered to be an altered coin worth face value only. On the other hand, if it's thinner than a normal quarter you could have what's called a lamination error. That happens when the outer cupronickel cladding comes apart from the pure copper core. You'd have to take it to a dealer who handles error coins to have it evaluated, but it could be worth $15 or so. A lamination error may not be noticably lighter or thinner than a normal quarter. Let an experienced dealer look at it.
A quarter
The double die error on the Wyoming quarter is so minute that it is very difficult to see without the aid of a magnifing glass. Errors that have a high value are usually those that are easily seen by the eye. Those like the Wyoming quarter are of interest to error collectors but the public usually has little interest in an error on a coin they can't look at and see it. Since it is the demand for the coin that sets its value, this difficult to see error will probably not have a very high value.
There were none. The quarter has been produced since 1796.
