Quote: "numisquare"In RIC the Arles issue has all four mint marks possible with the correct legend breaks. That same legend break is found on the Rome pieces, RIC p299 #33, 34, 37. See this coin for an example from Rome:

Thanks, did not see that (used Ctrl F "S-F across fields" and it didn't appear because this Rome coin have "S left, F right")
But I still think it's Arles, because I've found that there's a trace of the first mintmark letter, in a position not found on Rome coins.
By the way, I entered the Arles coin yesterday and Pejounet already validated:

He completed the coin info saying that there's actually four variants: PARL, QARL, SARL and TARL. With that, I saw that the remaining letter looks more like a P than Q, S or T, so it's PARL. Indirectly he helped on this case.
