Very nice!
As far as I know there were only two
sestertius obv. dies with this
legend, one with laureate and the other with bare-headed
portrait.
I have a bare-headed specimen from the same dies as yours, but unfortunately quite worn, only VG rather than VF like yours!
My laureate specimen, from NAC's Friedrich
Collection sale of 1995, is fortunately much nicer, about a match for your newly acquired coin.
