On 28 April 2021 the National Bank of Poland presented a new coin minted to commemorate the 230th anniversary of the 3rd of May Constitution. The 3rd of May Constitution was adopted on 3 May 1791. It regulated the legal system of the Polish-Lithuanian Commonwealth. It is generally accepted that the 3rd of May Constitution was the first modern written constitution in Europe and the second one in the world (after the American Constitution of 1787). It was adopted by King Stanisław August Poniatowski. It was designed to eliminate long-standing flaws in the political system of the Polish-Lithuanian Commonwealth based on free election and the democracy of the nobility. The constitution changed the state's system to a hereditary monarchy, significantly limited the democracy of the nobility by removing the right to vote and decide on matters of state from the landless nobility, introduced partial equality between the personal rights of the bourgeoisie and the nobility, and placed the peasants under state protection, thus mitigating the abuse of serfdom. The constitution formally abolished the liberum veto. The reverse of the silver coin depicts a fragment of Jan Matejko's painting "Constitution of May 3rd, 1791".  The reverse of the silver coin presents a fragment of Jan Matejko's painting entitled "Constitution of May 3, 1791". In the foreground there is the Marshal of the Four-Year Sejm, Stanisław Małachowski, carrying the text of the Government Act of the 3rd of May.  The obverse of the coin depicts the upper part of the title page of one of the early prints of the Constitution of May 3rd, published in the oficyna of Michał Gröll in Warsaw, and the coat of arms of the Kingdom of Poland from 1791.
