i don't have a link. it was on one of the shows I watched on History channel put out by the mint.
as far as I know they don't use fire to clean the planchets so a burn would be out of the question.(in my mind) I have seen a few of the new dollars with the cleaner or solvent on them the quarters as well.
i didn't know you was listing them anywhere but if you get a few sales great. good luck
Gary too
