This coin has something odd going on with some letters in the reverse legend. Two of the O's look more like G's...GENIG PGP; but the O in ROMANI looks normal.
Interesting- never seen anything like it!
Those "O"s are the strangest, but the L of POPVLI is more like a sideways "T" and ROMANI has a spurious I before the M making it ROIMANI.
What's wierd is how good the rest of it is, especially the obverse.
