ROMAN EMPIRE"Limes" copper denarius of Julia Mamaea 19 mm, 3.23 grams According to Numiswiki:"These are thought to be coins minted either officially or pseudo-officially on the fringes of the empire out of necessity. Perhaps they were used to pay soldiers on the extreme frontiers of the Roman territories or maybe to bolster the economy of regions far from the normal means of monetary distribution" They might just be copper cores of fourees after a thin silver wash has disappeared. ======================================COMBINED POSTAGE: USA: flat $5 fee per package, no additional postage for additional coins.
