How weight and silver quality shaped some Norse exchanges involving hacksilver and cut Islamic dirhams.
During the Viking Age (793–1066 CE), Norse warriors and merchants travelled from Scandinavia across Western Europe, Russia, and routes leading to Constantinople and Baghdad. In many exchanges, the weight and quality of silver mattered alongside the identity of the coin issuer.
In many Viking-age exchanges, weight and silver quality mattered greatly. That helps explain the use of hacksilver, although coins, local customs, and political authority also mattered.
Chopping Arm Rings and Silver Chalices
A trader could carry silver items such as ingots, arm rings, brooches, and fragments of larger objects. A piece could be cut to match an agreed weight on a portable balance.
Islamic Dirhams and Northern Trade
Trade along the Volga and Dnieper routes brought Islamic dirhams from the Abbasid Caliphate into Scandinavia. Hoards across the region show that these coins moved through long-distance networks and were often valued for their silver.
Some dirhams were cut into smaller pieces, known as cut dirhams, so silver could be measured for an exchange.
Testing Purity: Peck Marks
Some surviving coins show small peck marks, evidence that pieces of silver could be tested or examined before an exchange.
Hacksilver illustrates how weight and metal quality could remain important when coins travelled across political borders.
