Early Medieval Weight
This weight could have been used in the weight system employed by Scandinavian and Dublin populations. This system corresponded an ounce with 24gms. As this singular weight weights 12.98gms, it is possible that this is just part of a pair of weights or was used to represent objects that were half an ounce. Precious metals such as silver and gold were used as currency and the value was determined by the specific weight of the metal.[2] This allowed for coins and other precious metal objects to be used as part of a somewhat unified system. Scandinavians were thus able to use and trade objects obtained from many different empires with in their own communities and internationally.
Weights like this were used with scales which merchant would carry with them to trading towns. Some of the most famous of these emporia were Hedeby in now Denmark, Birka in Sweden and Dorestad in the Netherlands.
