Ludi Apollinares, games held in honor of the god Apollo which were made permanent by the moneyer's ancestor during his term as Praetor in 211 BC. On to this particular coin itself, I believe it to be an overstrike, which while not unheard of, is not terribly common with Republican denarii either, though there are other overstruck issues of this example known. You can see evidence of this most clearly below the chin, in front of the forehead and on the right edge of the reverse, though there are small signs all over the coin. This denarius also has some beautiful toning as well, probably at least in part from the previous collector storing it in an envelope for decades. The envelope also reveals some great provenance: Ex. Joel Malter, March 29, 1970. I unfortunately began collecting far too late to meet Malter, but from what @dougsmit has shared it sounds like he was a good person and a great dealer. AR Denarius(19.62mm, 3.9g), L. Calpurnius Piso Frugi, 90 BC, Rome Mint. Laureate head of Apollo right; "VIII" behind / L PISO FRVGI, Horseman, holding palm frond and reins, on horse galloping right; VI above, ROMA monogram below. Crawford 340/1, Sydenham 661, Calpurnia 12 Anyone else got any examples of this type to share? I'd love to see them!
