This is a bronze medal made by the Medallist of the Roman Emperors active in Milan in the last quarter of the 15th century. The obverse of this medal shows the Empress Faustina and the reverse shows Antonius Pius and Faustina seated.

Fuastina the younger was the wife of Marcus Aurelius, and the daughter of Antonius Pius and Faustina the Elder. Emperor Antoninus Pius, whose full title was: Caesar Titus Aelius Hadrianus Antoninus Augustus Pius. He was born Sept. 19, 86AD at Lanuvium, Latium and died on March 7 161AD at Lorium, Etruria. He was Roman emperor from 138–161AD. Of Gallic origins, he served as consul (120) before being assigned judicial administrative duties in Italy. He later governed the province of Asia (c. 134). He became an adviser to Hadrian and in 138 was made Hadrian's heir. On accession he had the deceased emperor declared a god; for such dutiful acts he was named Pius (“Pious”). He quelled rebellions in Britain and other provinces and built the Antonine Wall.
Mild-mannered and capable, he was the fourth of the “five good emperors” who guided the empire through an 84-year period (96–180) of internal peace and prosperity.
