This find was unearthed very recently (9 May) by Colin Barton. I’ve said on a number of occasions that detectorists dig up all manner of things, some of which have never been seen nor heard of until they surface. This is one such find.
Colin said it is 14mm in diameter and he thought it was made of lead. On one side is a face set within a beaded circle and on the other side are vertical and horizontal lines forming a mass of squares.
The face looks as if it could be Anglo-Saxon/Viking. An alternative is that the head could be meant to represent Christ within a halo. The imagery appears to be struck rather than cast. This would entail cutting a die for the side with the head, which would take some time to do.
So, what is this thing? I’ve no idea. Datewise, it might be over a thousand years old but could have been made relatively recently. I’d suggest it is old rather than fairly new, for why would someone want to make something like this over recent years? Plausible suggestions as to the age and identity of this find are welcomed.
