SEVERVS PIVS AVG, laureate head right / IVLIA AVGVSTA, draped bust of Julia Domna right. 20mm, 3.19 grams. RIC 273.

Rare and popular dynastic double-bust type. This is a core of a fouree denarius (silver-plated ancient forgery, made to pass into circulation as a real coin in ancient times). It was probably included in jewelry in ancient times or there was an attempt to pierce it.
