How weight and silver quality shaped some Norse exchanges involving hacksilver and cut Islamic dirhams.
In some Viking-Age exchanges, silver was valued by weight. The National Museum of Denmark's account of silver hoards notes that hoards could contain a mixture of coins, silver jewellery and bars, and that cut silver was used for payment.
Hacksilver is a modern term for cut or fragmented silver, including pieces of coins and other objects. Its use shows the importance of weighing silver in some settings; it does not mean all Norse exchange was bullion-only.
Chopping Arm Rings and Silver Chalices
Silver hoards include objects such as jewellery, bars and coins. In a weight-based payment, a portion could be cut off and weighed; the object was not necessarily made as coinage in the first place.
Islamic Dirhams and Northern Trade
Islamic dirhams are among the coins found in Scandinavian contexts. Finds establish contact across distance, but a coin's discovery in a hoard does not by itself identify whether it travelled by the Volga, Dnieper or another route.
Some coins were cut into smaller pieces that could be weighed alongside other silver. The term cut dirham describes a coin fragment; it is not a separate denomination.
Weight, Quality and Context
A fragment's weight helps explain how it could be used, but it does not by itself establish its silver purity, purpose or route. Those questions require examination of the individual object and its find context.
Hacksilver illustrates one way silver could function across political borders: as weighed metal, alongside coins and other forms of exchange.
