Circa 91 B.C. the Roman Senate passed the Lex Papiria de Assis Pondere, "The Papirian law on the weight of the as", often referred to as the Lex Papiria. The Lex Papiria reduced the weight of the bronze coinage to the semuncial standard, half the weight of the existing uncial standard, and also reauthorized the minting of the silver sestertius(though I'm mostly focused on the bronze here). Given the relatively tiny amount of bronze minted during this period compared to the massive silver issues the law seemingly had little real effect and find evidence suggests these bronzes were largely rejected by the citizens who preferred the earlier, heavier bronzes. Less than a decade later, perhaps because of how unpopular the new bronze weight standard was, the Republic ceased minting of bronzes entirely but the semuncial standard was eventually revived during the coinage reforms of Augustus who struck asses at a roughly semuncial weight standard of 11-13g. The coin I'm sharing today comes from a series minted after the passing of the Lex Papiria, represented by the letters "LPDAP" on the reverse. I'd had my eyes on this coin on eBay for well over a year but it was listed for quite a bit more than I wanted to pay. Thankfully the seller was willing to negotiate quite a bit and I was able to pick it up as a Christmas present to myself.
