Gallienus, 253-268. Antoninianus (Bronze, 19 mm, 2.81 g, 12 h), Rome, 267-268. GALLIENVS AVG Radiate head of Gallienus to right. Rev. DIANAE CONS AVG / Γ Antelope walking left. Cohen 165. MIR 716b. RIC 181. Wolkow 7a3. Minor spot of corrosion on the obverse and the reverse struck from a worn and clashed die, otherwise, about extremely fine.


Clashed dies occur when, during the striking process, no blank flan is accidentally placed between the dies. The reverse die then strikes the obverse die with such force that it leaves an impression, which can be seen on all subsequently struck coins - including our specimen. Usually, only faint traces of the obverse design are visible, but on this example the incuse head of the emperor is remarkably clear - a striking testimony to the immense forces generated during minting.
