done some digging on this, and found out why i couldn't identify it properly if you read the Legends around the edge where it is visible, you will see clearly they are Tudor, however just where the clip is, there is ZAB, and the legend on the other side matches ORE (IVTORE) opposite that OSV (POSVI) and also the VM of DEVM:AD however the curious thing is here, the only central detail i can see is a shield BUT as you can see the shield is on the same side as ELIZABETH from what i know of this is it came with some other silvers, and by the bag it came in, they were dirty. i have no reason to believe this is modern, and that big massive chizel dent in the middle is perhaps a test of silver rom the time? however this doesn't explain what the thing that looks like a bird is as it doesnt look like part of the shield cross design.
