Why is the left figure IDed as Perseus, though? The winged boots suggest Mercury I would think.
The boots are the sandals of
Hermes used by
Perseus. You are correct that they rarely appear on coins. The only other coin I have seen that depicts winged feet for
Perseus is a bronze of Hierocaesareia in
Lydia.
This is a beautiful coin. I almost placed a large bid myself!
According to Daniel Ogden, "When Lucan's
Pharsalia was published in 65 AD
Perseus was sufficiently well established as the founder of Tarsus in
Cilicia for the poet to attribute the epitaph 'Persean' to it." Ogden goes on to name the coin
types with
Perseus at Tarsos.
