I agree with you - looks like
SBCV 1854 to me.
The vast majority of Class G overstrikes are of
Constantine X's "
signed" (or non-anonymous) folles, so that is the first place to start. The pattern of the
loros over Mary's clothing makes it almost certain. The final confirmation
comes on the
obverse where you can just make out the outline of
Christ (
his head points toward 10:00 - that is "up" for the understrike) - with the right
side his hair on the understrike cutting across
his left eye and nose on the
overstrike (Class G). Since there aren't any other earlier bronze coins with
Christ on one
side and an emperor wearing a
loros on the other
side, 1854 is confirmed.
