I was really excited about the last CNG auction as they had a wonderful Roman republic reverse die. I've wanted an ancient die for some time, they don't come up for sale often and being RR just made it too sweet to pass up! (NOT MY DIE. My apologies if a coin talk pal won this) L. Calpurnius Piso Caesoninus and Q. Servilius Caepio. Circa 100 BC. Æ Denarius Reverse Die (27x25x10mm, 35.93 g). Blank / Incuse design for reverse: Two quaestors seated left between two stalks of grain. Cf. Crawford 330/1a; cf. Sydenham 603; cf. Calpurnia 5 (all references for denarius). Dark brown and green patina, verdigris on edge, corrosion. Fair. Possible contemporary counterfeit die, circa 1st century BC to 1st century AD. Extremely rare. I was ready to push things to the limit and even surpass the $300 estimate if needed. Day before the auction I was out bid and things went from bad to nuts when it sold for $1,300! $1,000 over the estimate!!! Does anyone collect dies? And if so, do they usually go for that much over estimate or is this just due to the COVID spending spree so many folks are on? Oh, and if you have any dies to share I would LOVE to see them!
