Coins issued by NBP

Based on the Regulation of the NBP Governor of 29 November 1994 (Monitor Polski No 64, item 575), on 1 January 1995 Narodowy Bank Polski put into circulation coins of nine denominations: 1, 2, 5, 10, 20, and 50 grosz and 1, 2 and 5 złoty.

The obverse of the coins features the image of the eagle established as the state emblem of the Republic of Poland. Under the eagle, there is a notation of the year of issue, which is the actual year the coin was struck, and an inscription RZECZPOSPOLITA POLSKA (Republic of Poland) along the rim.

The reverse contains digits denoting the nominal value of the coin, below which there is the name of the monetary unit and an ornament of oak leaves – different for each denomination.
1, 2 and 5 grosz coins are made from manganese brass (MM59), 10, 20 and 50 grosz coins and 1 złoty coins are made from cupronickel (MN25), whereas 2 and 5 złoty coins are made from cupronickel (the core of the 2 zł coin and the ring of the 5 zł coin) and from aluminium bronze (the core of the 5 zł coin and the ring of the 2 zł coin).
Depending on the nominal value of the coins, their edges are reeded (1 gr, 20 gr, 50 gr), plain (2 gr, 2 zł), interrupted reeded (5 gr, 10 gr, 1 zł) or irregularly milled (5 zł).

On 3 March 2014, Narodowy Bank Polski put into circulation new designs of general circulation coins of 1, 2, and 5 grosz denominations. A new common image was designed for the obverse. The image of the eagle established as the state emblem of the Republic of Poland was placed in the central part, and a semi-circular inscription RZECZPOSPOLITA POLSKA from left to right was placed below the eagle. Along the rim, there are stylised rings intersecting in the upper part and separated by the notation of the year of issue in the bottom part of the coin.  The material used for the production of these coins was brass-plated steel.

In 2017, Narodowy Bank Polski introduced general circulation coins of 10 gr (15 February 2017), 20 gr and 50 gr (23 January 2017) and 1 zł (20 February 2017) with the image of the obverse the same as in 1, 2 and 5 grosz coins put into circulation in 2014.

On 2 January 2020, Narodowy Bank Polski put into circulation 10 gr, 20 gr, 50 gr and 1 zł coins made from copper and nickel-plated steel. The image, edge, diameter and weight of the coins did not change.

The coins which are currently in circulation remain legal tender and will stay in circulation along with new coins.  

Narodowy Bank Polski also issues commemorative coins to commemorate important events, eminent people or historical anniversaries related, among others, to the world of art, culture, science, nature and sport. In April 2014, NBP ended the issue of 2 złoty coins made from Nordic Gold (CuAl5Zn5Sn1). Since May 2014, NBP has issued commemorative coins with a nominal value of 5 zł in circulation standard.
It should be remembered that all commemorative coins issued by NBP are legal tender in Poland. Their purchasing power is denoted by the face value on the obverse. However, irrespective of the amount of the nominal value, the coins have their collector value determined by the free numismatic market.
