This coin has a neat legend break on the obverse. There is a gap between V and G of AVG. It seems the engraver messed up a little.

It seems he belatedly realized he'd messed up with the legend spacing, so threw a gap in there to "make it better".
Judging by how "handsome" the figure on the reverse is, I assume it's meant to be Galeria herself, not Venus! ;D
Nice specimen of the type!
