Arizona Assay Office
Arizona Assay Office bars are highly collectible vintage silver bars, produced by Jack Stone in the late 1960’s. Although distributed by Paul Franklin, they were actually not a part of the infamous “Franklin Hoard” of counterfeit/reproduction bars that appeared around the same time. There are only 80 estimated pieces in existence.
