Please help identify this 1868 Badge/Medal piece.

Hi All,

I've been metal detecting an area with a lot of Victorian buttons etc. We got onto a hill where we had just found 3 x Victorian Artillery buttons when I picked this up. Any help identifying it would be greatly appreciated although there may not be much to go on except the word "Crowned" and the date 1868 (possibly 1858) and partial star shape I would assume.




Thanks in advance.
