A rare ort.
Both because of the ending of the titulature (PR:M+), and because of the shield of the Sas coat of arms - decorated, instead of straight or oval (only 1 reverse out of 17 varieties with PR:M in Shatalin).
Labrys ending in crosses, crown without shading, with base decorated -x-x-.
Mechanical cleaning at the top of the obverse. Nice reverse,
