Note: There are three competing theories as to the exact date of issue of this coin.

The seller said: "This rare issue of A.D. 136 was struck to commemorate the restoration of the Auguratorium on the Palatine, from which Romulus read the auspices for the foundation of Rome."

RIC II says that the coin was issued to mark the completion of the Temple of Rome and Venus in 137.

Curtis Clay, on 21 May 2010 on the the Forum Classical Numismatics Discussion Board, wrote: "ROMVLO CONDITORI is one of the earlier types in the H A COS III P P issue and should therefore be dated to about 132 on my chronology, because this type was copied on Eastern denarii of Hadrian, which were mainly struck earlier and only just managed to copy some early types of that last great issue of Hadrian before their production was stopped."

Curtis Clay's theory has direct evidence to support it, so is most likely to be accurate.
