This coin has a rare bust type for Aurelian, and it is facing right instead of left like the normal described by RIC...of course RIC V is very much in need of updating; there is probably a better attribution in Ripostiglio della Venera - Nuovo catalogo illustrato, Vol. II/1 - Aureliano by Sylviane Estiot - Venera Hoard Volume II Part 1 - Aurelian, but I don't have this book yet.
