   Scrap roof flashing.
I've been melting and casting roof flashing zinc since the late 1970s. But I couldn't find any just now, so I purchased a new bucket of scrap at Marco's scrap metal in Champaign in April 2002. Later I found many pounds of it in my parents' basement. This metal was melted down and poured into mini-muffin tins to make nice little coins.
