Two unique coins with multiple die stamps from Caucasus (13th century)
The authors publish two unique copper coins of the thirteenth century struck in the State of Shirvanshahs and in the Avar Nutsal with multiple die stamps. This kind of coins until recently has been known only among the Georgian medieval coins. The authors therefore offer a separate research regarding the origin of these rare items. They have discovered that during the period of the so called “silver famine” (in the Islamic world in 11th-12th cent.) production of multiple denominations did find an explanation from the point of view of the then economical situation.
