These type of disc brooches, where worn in pairs by Viking women. This was to fasten their apron dresses. I've had 3 Viking disc brooches over the years. The first was found about 50 feet away from this one, about ten years ago. It was about the same size, but a different design (borre style). It was though cast in bronze, it is now in the Retford museum. I think although different in decoration, they could be from the same person, maybe an odd pair. I would guess somewhere near are the remains of a long dead Viking lady, who was buried with her finest brooches. I would say that the brooch is probably 10th/11th Century. During that time, this area was in the Dane Law, that is controled and ruled by the Vikings. Thousands settled in the Dane Law at that time, the land was good to farm. The Vikings certainly left their mark on Yorkshire, culturally and language wise (broad Yorkshire language is very Danish in a lot of it's tone). This site every season gives up small amounts of Viking and Saxon metal work, there's got to be a nice coin lurking somewhere !.
