Stumped by a metal detecting find!

(Anglesey)

Hello Wil

And thank you for a very interesting and informative site.

I have the pleasure of metal detecting on this wonderful Isle and normally have no problem identifying the various items i discover, but recently i unearthed an item that has me stumped, two images are supplied,

It resembles a dog tag, the top loop is soldered suggesting age and it is silver, but its the inscriptions that are puzzling, on one side it says, Historical Ball, on the other there is an engraved crown and a engraved swirl design almost tribal and below that is stamped, Anglesey Castle June-15-03.

Firstly, I have no idea why it would state Anglesey castle rather than any of the named castles on the isle, is one of them refered to as Anglesey castle in history?

Do you know of any historical balls have taken place at any of the castles?

Does the crown and swirl design look familier to you in any of your research?

And lastly, I have no idea on the age of the item, it could be 2003 or 1703 silver items age very well in the ground, but the typeset and soldered loop make me think age,

I am truely stumped, any insight you could provide would be very helpful and appreciated.

Regards Jason.
