An interesting and rare forgery from the Lithuanian trojak era.
Modeled on the Vilnius trojak of 1593-1595, judging by the arrangement of the date and the treasurer's coat of arms. A coat of arms that ceased to be placed in 1598 (here the date is 1601). Additionally, a significant error in the reverse legend: TRI R PO instead of TRIP M D L, making it a coin of the Kingdom of Poland, not the Grand Duchy of Lithuania ;)
Low proof silver / bleached metal?, diameter 19.7 mm, weight 2.21 g.
