Unfortunately, despite the 100 year old provenance, it turned out to be a 19th Century cast. Happily, a couple of weeks later I acquired an example struck at Lugdunum. Vespasian Æ Sestertius, 24.45g Lyon mint, 71 AD Obv: IMP CAES VESPASIAN AVG P M TR P P P COS III; Head of Vespasian, laureate, r.; globe at point of bust Rev: CAESAR AVG F DES IMP AVG F COS DES II; S C in exergue; Titus and Domitian stg. front, each with spear and parazonium RIC 1132 (R). BMC 799. BNC -. Acquired from Romae Aeternae, June 2019. But I still continued to pine away for the Rome mint version of this special type ... until now. Finally, I have redeemed myself and added the Rome mint variant! Vespasian Æ Sestertius, 27.31g Rome mint, 71 AD Obv: IMP CAES VESPASIAN AVG P M TR P P P COS III; Head of Vespasian, laureate, r. Rev: CAES AVG F DES IMP AVG F COS DES IT; S C in field; Titus and Domitian stg. l. and r., with spears; Titus (to r.) also with parazonium, Domitian with roll RIC 143 (R). BMC 528. BNC 473. Acquired from NumisCorner, June 2020. An iconic dynastic sestertius struck during Vespasian's great bronze issue of 71. The type was struck both at Rome and Lyon (ancient Lugdunum) and announced Vespasian's intention to found a dynasty. Mattingly in BMCRE II calls it a 'famous' type placing the figures on the reverse as Titus on the left and Domitian on the right. While that is the conventional numismatic placement for the two Caesares, here we see the figure on the right holding a parazonium an attribute of an imperator, which of the two could only be Titus. Conversely, the figure on the left is holding something smaller (a book scroll?) that does not appear to be a parazonium. The reverse legend corresponds for this placement of the figures with the first half of the legend CAES AVG F DES for Domitian on the left, the second half IMP AVG F COS DES II for Titus on the right. The legend has caused confusion over the years with some numismatists creating the phantom title Designatus Imperator for Titus. The title COS is implied for Domitian after DES in the legend as a kind of numismatic shorthand. Gunnar Seelentag attempted to clear up the matter up in his Numismatic Chronicle, Vol 167 (2007) article 'Titus and the Supposed Title Designatus Imperator', but doubts remain. Curtis Clay has proposed that the traditional view of Titus on the left and Domitian on the right is correct, pointing out that both are holding a parazonium, theorising Titus's is hidden behind his body with only the handle showing. His arguments in full can be read here: http://www.forumancientcoins.com/board/index.php?topic=44488.0 The reverse type itself is fairly rare with only a handful of specimens coming to market each decade. Flavian dynastic types are far more common in silver. The acquisition of this piece was the completion of an important personal goal and a numismatic redemption. Do you have a similar redemption coin?
