Can't see it too well, but I'm assuming it's the one with the small crown perched like a tea cosy. If so, it was issued at 75 mm in pewter, white metal and lead. Both lead and WM turn up from time to time as uniface pieces, and once in a blue moon as inlays in furniture, tea caddies etc. I've seen the remains of the lead piece set into a garden bench in St Helier many moons ago.
