Size: 28.4 x 28.7 mm. Weight: 3.93 grams.
Reference: Met. 1214 to 16 variety., CCS 25g (page 526).
Grade: VF with typical weakness and difficult to read inscriptions. Attractively tone.
Obverse: Grand master kneeling beore a patriarchal cross on steps, with a castle behind and an "G" below the castle. In it's ideal form the inscription around would read, starting at the initial cross at 12 o'clock, FR IOANES FERDINANDI DEI GRA M, but the inscription on this coin is a variation on that, with some different abreviations, some letters llgate, and because of some weak areas I cannot quit work it out exactly.
Reverse: Cross fleury, and in it's ideal form the inscription around would read OSPITALIS IOHIS IRL'NI 9T RODI, but it a number of the letters appear to be ligate or completely on top of one another, making the exact wording hard to work out.
