Trajan, Rome mint, 116-117 AD.,
Dupondius (ø 25-27 mm / 11,90 g), brass ("orichalcum"), axes about coin alignment ↑↓ (ca. 170°), flan crack at eight o’clock on obverse,
Obv.: IMP CAES NER TR[A]IANO OPTIMO AVG GER DAC PARTHICO P M TR P COS VI P P , his radiate, draped bust facing right, seen from side.
Rev.: SENATVS POPVLVSQVE ROMANVS / S C (in ex.) , emperor, in military dress rushing to right between two trophies, looking back at the one behind him and extending his right arm to complete it, and holding spear pointing downwards in left hand.
RIC II, p. 292, 676 (scarce) ; BMC 1052 ; CBN IV, 111, 926 ; Coh. 356 (10 Fr.) ; MIR 586v (110 spec.) ; Strack 469 .
The two trophies probably represent Trajan's twelfth and thirteenth imperatorial acclamations which he won during his Parthian campaign of 115-6 AD, the latter for his capture of the Parthian capital Ctesiphon (Strack, p. 226), a victory which earned him the title Parthicus that is recorded in the obverse legend .
