Good find, Phil!
This is a Justinianus,
SBCV 165,
MIBE 96 = Tolstoj 331. You´ve got a
rare year-officina-combination of this
type, for
Hahn (
MIBE) lists only one reference-coin for year XUIII=18 and second
officina = B. But this doesn´t make you a rich
man The ragged edges are results of the minting process, not of use and time. It´s a question of
alloy, pressure and temerature.
