Cut bar hack silverFollowing my earier post on the Vikings I want to post a little about hack silver, a prevalent feature of Viking finds. Hack silver is, as the name suggests, cut up bits of silver objects, such as Islamic coins, jewellery etc, but also metal from these sources reformed into bars and strips or even droplets.
Globular hack silverI had thought that this material was then remanufactured into other items like jewellery or new coin of Viking type but it appears that hack silver itself was used as a form of exchange into the early 11th century and I wonder whether it is any coincidence that the three pieces that I have conform approximately to the weight of a half penny (dirhem fragment, 0.5 grammes), penny (globule, 1 gramme) and three halfpence (cut bar, 1.6 grammes), albeit at a time when the weight of a penny fluctuated greatly, even within a single series.
Islamic Ayyubid dirhem cut, Viking hack silverIt has been postulated that there became a social divide in the use of hack silver as a means of exchange through time where once it had been used universally within Viking culture with the lower strata continuing to use it whilst the more elite began to become a more monetized society. With increasing monetization the range of weights of any particular series of coin became more fixed and the value for exchange was done less by weight and more by recognised value.
Islamic dirham of the Ayyubids, 192 AHThe use of hack silver as a method of exchange seems to have petered out during the 11th century and this has been linked to the debasement of the Islamic dirhems of the Fatimid dynasty.
