Mint art of the rarer of the two denominations with the Brave.
The 10 and 20 zlotys with the image of King Boleslaw Chrobry are a design by Zofia Trzcinska-Kaminska, selected in a 1925 competition. The first gold coins were minted in 1926, albeit with a date commemorating the 900th anniversary of the coronation of the Brave. They were made in accordance with the first monetary reform of the Second Republic, but due to the value of gold being higher than the denomination of the coins, they were not put into circulation.
Gold, diameter 21 mm, weight 6.45 g. (catalog).
