This type was issued upon the completion of the restoration of the Great Provision Market on Caelium Hill in A.D. 59: the Macellum Augusti, also known as the Macellum Magnum. It was built by Augustus and restored by Nero. Part of it was later transformed to church S. Stefano Rotundo by Pope Simplicius.
