I have a Probus antoninianus with a mint mark I can't seem to find in my older copy of RIC.
The reverse is RESTITVT ORBIS with design of a woman presenting a wreath to Probus.
The mint mark is XXI . II and there is no star in the reverse field. I've looked at all the possibilities for RIC #731-734 (Siscia mint) and nothing seems to match.
Any possibility with a dot after the XXI has a star in the reverse field.
Could this be an unlisted variant or am I missing something? Any help would be appreciated. Thanks.
