Thanks Guys for all suggestions, I can only add one thing to my first post, this coin is a metal detection find, that is the reason why is so worn, found on a battlefield from IWW, maybe a British soldier hold this coin for luck, there is many possible ways how she ended such a long trip in Polish soil. Anyway I will send this coin to the Curator at the Royal Mint,and after that I will let you know how the things looks like. Once again thanks for help. Mike
