Gallienus

Obv: GALLIENVSAVG - Head right with radiate crown.
Rev: DIANAECONSAVG - Gazelle walking right. XII in exergue.
Rare reverse several times over! The right-facing gazelle on an XII-officina coin is uncommon, but the long wavy horns growing straight back are uncommon for any of the gazelles. Plus, the gazelle's nearer hind leg is advanced, rather than the far one. This is a feature that ONLY appears in officina XI and was totally unknown in the Cunetio Hoard.
