In the 1991 in Warsaw, on Stoczkowska Street a hoard of coins was found which later was partly dispersed. Part of the hoard was purchased by the Royal Castle in Warsaw and is kept in its Numismatic Cabinet. The finding is consisted chiefly of 'polturas' from the third decade of the 17th century, primarily crown coins with an admixture of Prussian, Elblag as well as Riga coins. Smaller denomination coins are represented by only dozen or so pieces of different schillings as well as groschen and also two ternars of Poznan and Loobzenica. The hoard comprises also coins of higher denomination, first of all three-groschen coins, six-groschen ones nad several orts. The thaler coins have a western provenience (chiefly Netherlands and also Bohemia, Saxony and Switzerland). The oldest coin in the deposit from Grochów is a Bohemian half-thaler of Rudolph II (1576-1612) from 1611 and the youngest - Gelders lion thaler dates back to 1641. The deposit from Warsaw-Grochów is a typical hoard from before the middle of the 17th century.
