heres another good one out of the redbook. lamination-a flaw whereby a fragment of metal has peeled off the coin's surface. this defect occurs when a foreign substance, such as gas oxides or dirt, becomes trapped in the strip as it is rolled out to the proper thickness. lamination flaws may be missing or still attached to the coin's surface. minor flaws may only decrease a coin's value, while a clad coin that is missing the full surface of one or both sides is worth more.
spock: The value is dependent upon the coin. Large & small laminations for war nickels are very common, and little or no value. A lamination that causes a split planchet on a V-nickel! That is valuable.
All error coins are becoming a thing of collectors. There are now error collectors and at coin shows even the slightest error is selling for a lot more than you would expect. lamination coins do sell regardless of the amount of lamination as long as the date and mint mark are visable.
