Habe ein email an forumancientcoins geschrieben und auch sofort eine Antwort von Lech Stepniewsky bekommen, (ich hatte ihm Ticinum 29b also nicht die richtige RIC Nummer angegeben

). An catbikes habe ich nicht geschrieben, da es jetzt ja geklärt ist.
Vielleicht interessiert Euch seine Antwort:
"TICINUM 29b has no dot in mintmark. mean probably TICINUM 33b.
And, yes, your coin is a minor variant of 33b. It seems that there is
also a trace of dot to right. Maybe something went wrong during the
die-cutting? Or maybe the die was clogged and then repaired and the
engraver preferred to make a new dot to left because it was easier and
safer than to correct the old one? Of course, it is only a
speculation.
Thank you very much for the pictures. Who should be credited as the
owner of this coin? "
Schöne Grüße
