Very rare. Old cabinet tone and good very fine

According to Oliver Hoover, the monogram might possibly be a retrograde version of 1505.1. Taking this together with the treatment of the diadem ends, which is exclusive to Seleucia on the Tigris in the period, he thinks the coin is much more likely to be Seleucia on the Tigris than something else. The quality of the portrait makes an imitative mint seem unlikely, notwithstanding the retrograde N. The portrait seems to represent a transition between that of 1505.1 and 1505.2. It has the hornlike lock and gap in the hair at the temples of 1505.1, but the tight curls of 1505.2.
