RPC II p. 125, this section written by
Metcalf:
"There are some undated coins which appear to precede those dated
cos II, and it is possible that they were minted in late 69 or else early 70, but there is nothing to demonstrate striking in 69, and the date of 70 would be implied...if some of the
reverse designs are derived from those used at
Rome in that year."
p. 126: "The designs of the heads and the standing figures of
Titus and
Domitian are the same as those used on the earliest coins of
Rome (
BMCRE 1, 6)."
The
aureus BM 6, however, with FILI retrograde in
rev. exergue, may itself be Eastern.
