Severus Alexander AE Limes Denarius, 226 AD OBV: IMP C M AVR SEV ALEXAND AVG, Laureate, draped bust right. REV: ANNONA AVG, Annona standing left, holding corn-ears over modius and cornucopiae. Limes version of RIC 65; Sear 7903. "limes" is Latin for "'Pathway", a word which came to be used to denote a military road along a frontier and in due course the official boundary of a part of the Roman Empire. "Limes" were minted by offical mints on the borders of the empire to make up for local shortfalls in currency. They were normally minted in bronze due to the shortage of silver in these areas due to continuous barbaric invasion and unrest that made large shipment of silver unsafe.
