I really like Licinius I coins, and this one is no exception. It is :-
LICINIUS I AE Follis.
Obv: IMP C VAL LICIN LICINIVS PF AVG, radiate, draped & cuirassed bust right
Rev: IOVI CONSERVATORI, Jupiter standing left, chlamys across left shoulder, holding Victory on globe & leaning on sceptre, eagle with wreath left, captive right. X over II Mu in right field.
Mintmark SMKB
RIC.VII.Cyzicus.15
My problem is that this coin is much better 'in hand' than under magnification. What has made the surface like it is?
