After Constantine died in 337, his sons issued posthumous coins in honor of their father. Constantine was the last Emperor to be consecrated and deified on coins. Eusebius also wrote about one of these posthumous coins:
"At the same time coins were struck portraying the Blessed One on the obverse in the form of one with head veiled, on the reverse like a charioteer on a quadriga, being taken up by a right hand stretched out to him from above." Life of Constantine IV 73
