Here's a coin I added to my collection recently: an unlisted variant of a very rare "army type" denarius struck under Hadrian. HADRIAN, AD 117-138 AR Denarius (18.6mm, 3.00g, 6h) Struck AD 130-133. Rome mint Obverse: HADRIANVS AVG COS III P P, laureate bust of Hadrian right, with slight drapery on far shoulder Reverse: MAR-TI, Mars, helmeted, standing facing, head left, holding inverted spear in right hand and resting left hand on shield References: RIC II.3 1588 (R3) var. (A2 bust); RCV – ; ERIC – . Light toning, somewhat rough surfaces, flan flaw on obverse, good portrait. An unlisted bust variant of an extremely rare type, apparently known from a single obverse die. In my researches I was able to find only two other specimens, both from prominent collections. This type, with its martial theme and inscription to Mars, the god of war, is included in the rare group of "army type" denarii struck under Hadrian around the time of the Bar Kokhba Revolt.
