Very nice luster, especially on the reverse. Internal disc corrosion (puffballs), but coin with preserved natural sound.
Variant identified as unique by Gregory Romanczyk - with a colon between PRIM9 and REX and after MONETA.
A distinctive type distinguished by the presence of a Gothic crown at the top of the obverse (simple in design, open). Minted only in 1526 and early 1527.
