Those are rolls sold to the public from the U.S. Mint . Each roll is brilliant uncirculated coins . A dealer or e-bay seller gets them and sells them at a premium above the mints price . Yes you can find errors with these rolls as with the same percentage of Bank wrapped rolls from a bank . I tend to disagree with Big-Kingdom about the U.S. Mint wrapped rolls of any denomination not increasing in value in the long run .

In Memory of Butch L.
and Jim U. rest in peace .
