Very rare and desirable reverse type with the classic roman theme depicting she-wolf feeding Romulus and Remus. Alfoldi describes 4 variants of this reverse type depending on the position of the she-wolf (left or right) and the position of she-wolf's head (turning right or left).
This particular variant is unpublished (unlisted both in RIC and Alfoldi) and apparently only the second known (the first example being in C. Oliva collection).
