That is probably the most beautiful Victory sestertius of Septimius Severus I have ever seen - a photo of it goes in my loose leaf -
The first Septimius is very rare but I cannot recall ever seeing the second one on the top row far right - do you know the RIC #? is that Anonna with corn ears and patera over alter? IMP III I think.
I have two to contribute. One has a misshapen finish the other has a deep green patina Gaius Vibius Trebonianus Gallus.
