Umayyad Caliphate Æ Bronze Fals, Arab-Byzantine Type: Hims mint. Abd al-Malik AH 65-86, 20mm, 1.8g

These early islamic coins were struck in the style of contemporary coins of the Byzantine Empire around the time of Constans II.  They represent a unique style blending Christian Byzantine motifs (cross on the emperors crown) with Greek and Arabic inscriptions.  These coins were issued very early in the history of Islam; within 50-100 years after the death of Muhammad.
