The third doesn't need any analysis beyond its crude
style to deem it unofficial, not to mention that it's significantly underweight at 2.1g.
What I do find interesting about this coin is that no such
bust is recorded in
RIC VII. It's obvious that the engraver used as a model, a coin with
bust G2 (right, laureate,
cuirassed, with spear over right shoulder), but
engraved the die in the same orientation as the coin, giving us a horizontally-flipped version of G2.
I also find it comical that he
ran out of room in
exergue for the
mint mark and stuck the L of TARL to the right, next to the
inscription. You wouldn't want to leave out a letter - that would make the coin just plain wrong!
