I assume this would be the right forum to post this in. So I've decided to save pre-1982 copper pennies for their copper content. I know that some pennies from 1982 are copper and some are zinc, so I only keep the copper 1982s. So here's my question. Should I keep my copper 1982 pennies seperate from the pre-1982 pennies? If/When it becomes legal to melt them down, do you think whomever I sell them to would not accept any 1982 pennies because some were minted as zinc? Do you think they'd want them seperate to sort through? I know there are large-scale sorting machines out there that could verify that all the pennies are copper...but I don't know of any scrap yards that have one of those.
