My latest addition is a nice illustration of why it is important to have a coin in hand when there is a tricky attribution afoot. Titus Æ As, 11.89g Rome mint, 80-81 AD RIC 233 (R3). BMC - . Obv: IMP T CAES VESP AVG P M TR P COS VIII; Head of Titus, laureate, bearded, l. Rev: PAX AVGVST; S C in field; Pax stg. l., with branch and cornucopiae Acquired from Praefectus Coins, December 2018. The various stock Pax types struck for Titus are general carry-overs from Vespasian's reign and are normally seen on Titus' sestertii and asses. This as features a rare variant of the standing Pax type. She is seen here holding a cornucopiae instead of the much more common variant with caduceus. This reverse type with AVGVST instead of AVGVSTI is also extremely rare - only one specimen was known when the new RIC II.1 was published. Judging from the seller's photo I assumed this to be the 'AVGVSTI' variant when I purchased it. After examining it in hand I realised that what I thought was an 'I' in the photo was actually a minor ding, making this coin the second example of the type with 'AVGVST'. Needless to say, a most pleasant surprise! Here is an image of the reverse I snapped with my phone. Feel free to post your 'surprises'!
