Very rare obverse legend with the INVICTVS title (invictvs = invincible). The variant with the additional letters P F (Pivs and Felix) in obverse legend is particularly rare.
The Invictvs title was first introduced in regular coinage by Aurelian. Probus later borrowed and used the title on coins struck at Serdica, Ticinum and Siscia mints.
