Yes - as it happens I am looking at that Topic now also. Need a picture of the other side as well. I found three pages of 1 grano coins, and there are many varieties. A closer-up picture the better.
I can not make out much of the lettering - is it ...
SVB HOC SIGNO MILITAMVS = Under this Sign We Fight
or maybe
IN HOC SIGNO MILITAMVS
and as you know the date is in the angles of the cross - like this 1726 coin ...

Maybe I should have written on that Topic instead, but here will do I guess.
