According to Sextus Aurelius Victor, he later fell into Caesar's hands and was put to death. This event is unverified by other contemporary sources, but may explain why his son, P. Cornelius P. f. P. n. Lentulus Spinther, joined Caesar's assassins, Brutus and Cassius, and struck coins for them during their civil war against the forces of Marc Antony and Octavian. Like his father before him, the younger Spinther also put his own name and nickname 'Spinther' on the reverse of his coins, the obverse of which feature the head of 'Liberty'.
