The letters following the number (1 A, 1 B..) classify the coins according to their quality of representation.

Obverse legend copied: DN HLVDOVVICVS IMP AVG

Reverse legend copied: NVMVS DIVINVM

On the reverse, in my opinion, the form M at 6 o'clock is a representation of the ribbons of the crown, these lines being inclined and joining towards the crown.
