Parthian Empire, under Vologases IV, AR tetradrachm, SE 464, month Apellaios (November 152 AD), Seleukeia on the Tigris mint. Obv: Diademed and draped bust l., wearing tiara; B behind. Rev: [SEΒΑΣΙΛΕΩΣ / Β]ΑΣΙΛΕΩ[Ν - ΑΡΣΑΚΟY / O]ΛΑΓΑΣΟ[Υ - ΔΙΚΑΙΟY - Ε]ΠΙΦΑΝΟY[Σ / ΦΙΛΕΛΛΗΝΟΣ], date: ΔΞY – ΑΠΕΛΑΙΟΥ; Vologases seated l. on throne, Tyche standing r. before him, presenting a diadem. 27mm, 13.81g. Ref: Sellwood 84.13. So, why did I buy this? First of all, I consider my Greek and "Eastern" collection to be more or less the size I want it to be, and I have stopped adding bargain coins to it. Yet, there is a carefully compiles wish list of coins that I would like to permanently house in my trays. The third item on that list read "a really nice Parthian silver coin" – checked off, I'd say! This is my first and (so far) only Parthian coin, and I doubt that I'll start to seriously collect in this field soon. Yet, I wanted to have at least one coin to represent this great empire and foe of Rome. Vologases IV, the only Parthian ruler to declare war against Rome and not vice versa, thus seemed a fitting choice to me. Also, the chunkiness of a tetradrachm in hand is something special, and I really like the grim portrait and Tyche reverse on my example. Please show your Parthian coins, "one of a kind" purchases, or anything else you deem relevant!
