Nummi Scyphati Öffentlichkeit Deposited
A name given to such pieces as present the appearance of a shallow bowl, due to a convex die having been used for the obverse, and a concave one for the reverse.
These nummi scyphati , as they were called, made their appearance as early as the second century B.C. among the Germanic tribes inhabiting what is now Bavaria and Bohemia. Later, this type of coin was extensively employed by the Byzantine Emperors of the eleventh and twelfth centuries.
