This coin was in a bag marked Canadian but I suspected it was U.K. ..I ended looking under all english speaking countries and cannot locate it, funny there is no writing just a date.
Here is an ebay auction that seems to be selling the same token. Auction "Waltamstow, Essex England halfpenny token issued in 1813 by the British Copper Company who had smelting works at Walthamstow" Taken from auction looks like Cheryl beat me to it
