I cannot find anything specific for you but it is probably an English or Irish Half (Peny) Penny trade token from the 17th century. Pity it isn’t dated.
Half Peny, unit of currency and Millstreet, probably a place name around the edge and the traders initials centered.
reads Edward De Whorre Intvrv (inturum) which is probably the trader. Coat of arms centered.I cannot find any reference to this at the moment.
Possibly English Civil War period or soon after 1640 to 1680.
