OGN numismatique gives the legend of reverse: SCI MARTINI. I agree with the start; the letters M and A are apparently mixed because we see a horizontal bar between the last two legs of the letter M. But the end of the legend, in my opinion, ends with the letter N. No letter I is visible or else they are confused with the letter N but impossible to dissociate ... It is therefore more likely to be MARN.
