Copper-alloy, 9.55 grams, 55.72 mm. 10th-11th century AD. Viking and Later Anglo-Saxon keys comprised a circular loop developing into a thick shank developing into a headplate. The present example includes the loop complete with two lateral horns, the round-section shank with collar on the upper surface, and the lower part of the head with its quadrangular void, terminal and delicate T-shaped finial. Keys of this type are brittle and easily damaged at the extremities due to the thin metal surrounding the voids; this is a complete example.

The women in a Viking household looked after the most valuable items in the house. In many Viking homes, this would be a large chest or box with an iron lock. The wife was in charge of the key to this chest.
