Scandinavian silver coin hoards

Timeline

1. 800–1000Birka · SwedenIn the 9th and 10th centuries, Arab silver entered Scandinavia in large quantities via the Volga–Dnieper trade routes, buried together with Byzantine and Frankish coins. Coins, arm rings, and hack-silver in hoards were valued by weight, forming a silver economy without a unified mint, supporting Scandinavian trade expansion and overseas colonization.
2. c. 1000–1130Denmark · DenmarkAfter the 11th century, English pennies became the main component of Scandinavian hoards; the Danish royal house and church promoted local minting, and hoards mixed silver coins of multiple countries with cut hack-silver. Silver still circulated by weight, but the convergence of coin types reflected deepening trade integration within Christian Europe.
3. 1131–1140Gotland · SwedenIn the 1130s individual silver hoards were still buried in Scandinavia, consisting mainly of English, German, and local Scandinavian pennies, with Arab silver markedly reduced. The hoards may be linked to warfare, tribute, or changes in land tenure; archaeological stratigraphy shows a transition from the old hack-silver economy to royal minting systems.
4. c. 1150–1200Scandinavia · Northern EuropeFrom the second half of the 12th century, large mixed silver hoards decreased markedly, in connection with the standardization of royal minting and the church's shift toward donations of buildings and land instead of offerings. Earlier hoards have become core archaeological evidence for studying Viking silver flows and the medieval economic transformation of Scandinavia.
