Hyperpyron

Hyperpyron of Emperor Manuel I Komnenos (r. 1143–1180), showing its typical scyphate (cup-shaped) form.

The hyperpyron (Greek: νόμισμα ὑπέρπυρον nómisma hypérpyron) was a Byzantine coin in use during the late Middle Ages, replacing the solidus as the Byzantine Empire's standard gold coinage in the 11th century. It was introduced by emperor Alexios I Komnenos.
