Ex Gorny & Mosch 142, 10 October 2005, lot 2494. After major victories, the army saluted the emperor "imperator" ("commander"), entitling him to celebrate a triumph in Rome if the Senate decreed one. This sestertius of Trajan, a similar sestertius with IMPERATOR VIII, and a similar aureus with IMPERATOR VII, are the only Roman coins to depict such a salutation. These three acclamations commemorated the first three victories of Trajan's Parthian war, IMP VII being accorded for his conquest of Armenia in 114, IMP VIII and VIIII for the first two victories of his second campaign in 115.While many examples of this type have come into the market, virtually every single one of them has been tooled. This coin is excessively rare in that it has never been tooled, with a beautiful olive-colored patination, and a flawless, beautifully struck obverse and reverse. MS
