possible crusader coin unable to identify [opgelost]

18 mm 0.8g

Obverse: Tower center of field crescent to the left and to the right, Latin inscription around the outside.

+ . . O M N E V S I S

Reverse: Cross with o in first quadrant and a star with a point at its center in the 3rd quadrant. Latin inscription around the outside.

+ T .  .  . V . S V S C O M E S

Any help would be gratefully received. Jeremy

I am seeing + I ? MMENSIS on the castle side.

And I think the first letter is A on the cross side, so + A-–CV -- SVS  COMES as the second word on the cross side.

(I thought ALFONSVS, but don;t think that's right).

Maybe also consider a French feudal?

Edit:  I wonder if yours is a legend variant with just + ROMMENSIS (with a very wide R). 

And, nice coin!

Added:  Your variant has the legends switched (obverse to reverse). Duplessy 822:  https://www.acsearch.info/search.html?id=3149730
