Byzantine Empire coinage from Anastasius I to the 13th century CE. The new denominations organized by Anastasius were: Gold Solidus, Half Solidus, and Third Solidus, and copper Follis of 40 Nummi and its fractional parts down to a Nummus. NOTE: Toned coins or coins of dark color (copper, bronze, toned silver, etc.) do not scan well. It is recommended that you adjust the light/contrast settings of the scans to see details.
