Watch List notes:

Otho. Denarius; Otho; 69 AD, Rome, Denarius, 3.04g. BM-4, pl. 60.3 (same obv. die); C-5 (citing BM, 20 Fr.); RIC-6. Obv: IMP OTHO CAESAR AVG TR P Head bare left. Rx: PAX ORBI[S - [T]ER[RAR]VM Pax standing l. holding branch and caduceus. Very rare with portrait left. Of the 47 denarii of Otho in the Reka Devnia hoard, only one had portrait left, and that one had the Securitas reverse type, not Pax like our coin. The Pax type with portrait left is missing from the Paris collection, so Cohen had to cite this variety from the BM specimen, which is from the same obverse die as ours. In his corpus of over one thousand images of Otho denarii in museums, publications, and online, Jyrki Muona found only five coins like ours, making it the second rarest Otho denarius. Ex Jyrki Muona Collection, with miniscule drill hole in edge, because the metallic composition of this coin was tested and published by K. Butcher and M. Ponting, Metallurgy of Roman Silver Coinage, Nero to Trajan, 2014, p. 253.. VF
