Oh what the heck, I'll add this Vespasian 'snake' denarius to the fray. Vespasian AR Denarius, 3.27g Rome Mint, 75 AD RIC 776 (R). BMC 169. RSC 369. Obv: IMP CAESAR VESPASIANVS AVG; Head of Vespasian, laureate, r. Rev: PON MAX TR P COS VI; Victory, draped, holding wreath extended in r. hand and palm upright in l., standing l. on 'cista mystica', on either side of which is a snake, coiling up on it's tail, facing inwardly Ex Berk 145, 14 September 2005, lot 232.

WoWiE Bing! (Let me just wipe the drool off my chin) The head with the siddling snakes on the reverse of that thar coin, as you know, is none other than Octavia! The sister of Rome's 1st emperor and wife to that fella on the obverse, Julius Caesar's homeboy, Marc Antony. What a story that coin tells. That's a beauty. And in good condition ta booty!
"Cista mystica" (scroll up this page for a couple of examples)-- frequently found on ancient coins. Excerpt from the Numiswiki entry for cista mystica:
