Ex SKA Bern 2, 1984, 375 and NAC 83, 2015, Student and his mentor part III, 232 sales.We are not sure whether the denomination litra is correct. Prior to 1984 only one specimen of this coin was known, in the Museo Archeologico of Naples. That year a second specimen, supposedly coming from Spain, appeared in a sale of Credit Suisse Bern. Since that time, at least six or seven specimens have appeared in the trade, all presumably with the same origin. RBW PART I has suggested in NAC sale 61 that this is a silver As.
