Diocletian AR Argenteus. Siscia, AD 294-295. Obverse: DIOCLETIANVS AVG, laureate head to right Reverse: VIRTVS MILITVM, four tetrarchs sacrificing over tripod before city enclosure with eight turrets; pellet in doorway. Reference: RIC VI 32a. Weight: 2.64g 6h. Diameter: 17,7mm If I have to asess the coin myself, I would call this a real gem. It was also a real bargain. I bought another Diocletian argentus less than a year ago, but just couldn’t turn this one down. Here’s the «old» Diocletian in AR coin, which even made my top 10 list last year: Diocletian, 284-305 AD. Argenteus. Nicomedia. Obverse: DIOCLETIANVS AVG. Laureate head right. Reverse: VICTORIAE SARMATICAE / SMNΓ. Camp gate, with four towers and star above open door. Reference: RIC 25a, RCV 12616 Weight: 3.21 g. Diameter: 18 mm. I’ll probably keep both, at least for a while, as they represent the two major types of argenteii. The next upgrade was my Valentinian I silver coin. I’ve never been very happy with this one, typical bottom feeding purchase many years ago: Valentinian I, Siliqua, Rome, A.D. 364 - A.D. 367 Obverse: D N VALENTINI-ANVS P F AVG: Bust of Valentinian I, pearl-diademed, draped, cuirassed, right Reverse: VOT/V/MVLT/X within wreath Mint mark: L B Reference: RIV IX Rome 10b The new upgrade makes me smile every time I look at it, however: Valentinian I. AD 364-375. AR Siliqua, Lugdunum (Lyon) mint, 2nd officina. Struck AD 364-367. Obverse: Pearl-diademed, draped, and cuirassed bust right Reverse: Valentinian standing right, holding labarum with plain shaft and Victory on globe; SLVG. Reference: RIC IX 6a; Lyon 12; RSC 18-19†c. Size: 17.5mm, 1.96 g, 6h. Conservation: Toned, attached lamination flaw on reverse. Good VF. I’m still hoping to add one or two of the remaining emperors in the silver set this year, but I really enjoy these upgrades too. What about you? Have you had any upgrades on areas you are collecting so far in 2021?
