Graham,
Judging from several dozen specimens in
CoinArchives Pro, you appear to be correct: this
rev. legend is usually broken NOBI - LITAS, with the goddess'
head and the top of her
scepter coming between the I and the L.
However, that doesn't make your coin a
hybrid, just an unusual placement of the
legend by at least one engraver on one die. It doesn't change the
RIC number, since
legend breaks are usually not even recorded in
RIC volumes before the Tetrarchs.
On some
rev. dies the I - L break is preserved, but the letters are so close together that the
legend almost looks unbroken: see example below.
Your coin could well be authentic, but the
style and surfaces don't make me 100% convinced. It would be nice to find other comparable examples.
