State quarter lamination errors retail for about $10.
This is called a 'Lamination' error and a statehood quarter with this error is worth $50.00.
This coin could be a coin with a 'Lamination' error, if so it could be worth as much as $18.00.
You have what's called a lamination error. It occurred when one side of the coin's outer cupronickel cladding fell off due to a poor bond with the inner core of pure copper. Lamination errors can occur before or after the coin is struck, whenever the bond fails. Current retail for this error on a pre-State Quarter design is about $10.
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.
It's not exactly clear what you mean by "no sides" If you mean that the outer nickel-colored cladding is missing, leaving the inner copper core visible, that's called a lamination error and could be worth about $10. A lamination-error coin should be quite a bit thinner and lighter than a normal quarter. If not, i.e. it's the same thickness and weight as a normal quarter, it's either been plated or exposed to a chemical that changed its color, and is only worth 25c. If I didn't interpret your question correctly, please post a new one with more details.
If it is copper on only one side you probably have a lamination error. This happens when a coin's outer clad layer fails to bond properly with the copper core. Lamination errors are thinner than normal coins because they're missing a layer of metal. Lamination-error Bicentennial quarters retail for about $25. If you have a coin that's the same thickness and appears to be solid copper it's more likely to have been plated. In that case it has no extra value.
A good 1995 error quarter can be woth up to $20 in good condition
You have what's called a lamination error. Sometimes the outer cladding on a quarter, nickel, or dime does not stay bonded to the copper core, a bit like taking one side off an Oreo cookie. The cladding can come off before or after the coin is struck. Lamination errors among state quarters are popular and retail in the $10 to $15 range.
All circulating U.S. state quarters are worth 25 cents.
This is called a lamination error and occurs when one or both of the coin's cupronickel outer clad sides failed to bond properly to the copper core. Currently, state quarter lamination errors are retailing in the $12 to $15 range.
It depends. If the coin is thinner and lighter than a normal quarter you may have a "lamination error" that happened when the outer cupronickel cladding separated from the copper core. A lamination error can retail for $15 or so. If the coin is the same weight as a normal quarter, it's probably been plated by someone with a knowledge of high-school chemistry. Then it's an altered coin worth 25 cents.
Value depends on what kind of error. please be more specific
