The reverse of the 10 złotych of 1971 shows the Silesian Insurgents Monument in Katowice and the dates 1921–1971: the coin marks the 50th anniversary of the Third Silesian Uprising, which decided how much of Upper Silesia would become part of Poland.

The uprising broke out in May 1921, two months after the plebiscite, and in 1922 the eastern part of the region, including Katowice, passed to Poland. The Katowice monument by Gustaw Zemła, unveiled in 1967, appears on the coin together with the insurgents’ cross and the inscription 50 ROCZNICA III POWSTANIA ŚLĄSKIEGO.

The coin was designed by Wacław Kowalik, whose initials WK are on both sides. The obverse carries the White Eagle, the mint mark MW and the value «ZŁ 10 ZŁ». Two million were struck by the Mint of Poland in Warsaw.

For a collection on Silesian history or monuments on coins, this is a key issue. Very Fine (VF): wear shows on the high points of the monument, but its silhouette, the dates and the lettering read clearly.

Numismatics begins with a single coin and continues in the VPcoins catalogue.
