History of the Prague Grosz

The Prague Grosz began minting in 1300 by the Czech King Wenceslas II. That year, silver veins were found near Prague (in Kutná Hora) and silver mining began – at the time they were the largest silver mines in the world. This allowed the king to reform the coinage. During the 13th century, the most common coin in medieval Europe was the denarii. Their quality fluctuated and by this time the weight was already below 1g, while the purity often fluctuated below 50% of the silver content.

Wenceslas II was inspired by Tours, where the French king minted a gros tournois coin. The name itself comes from “large denarius”, later only the “large” (gross) remained. The grosz was a large and heavy coin (30mm 3.5-3.7g silver, with a high purity of around 93-95% pure silver. Due to the richness of the Kutná Hora mines, the grosz quickly became the standard silver coin in Central Europe.

After Prague, some other cities minted grosz, mainly in Germany, but the Prague grosz was long considered the most reliable and valuable. For example, the exchange rate was in effect when one Prague grosz was worth two Meissen grosz. To give you an idea, let’s try to imagine the value of the Prague grosz as about 10-20 euros in today’s world.

There were also smaller coins – half-grosz were also minted, old denarii remained in circulation, which had a value of around a quarter of a Prague grosz, and new small silver coins (parve) were minted, where one Prague grosz contained 12 parve. The Prague grosz became a unit of account – salary was usually calculated in Prague grosz groschen, everyday purchases were converted into groschen and its fractions.

If you are wondering why gold coins did not catch on, it is because their price was too high. If we try to imagine the value of, for example, one gold florin of John of Luxembourg or a gold ducat of Charles IV, it will be more like around 500-1,000 EUR. Which means that most people never held a gold coin in their hands. Gold coins were used to buy houses, estates or other really expensive things and it was the currency of the nobility. Silver coins were much more suitable for everyday life.

During the Hussite Wars, the minting of groschen ceased and was only resumed by George of Poděbrady, but by then its weight had dropped to about 2.5g and the fineness was only around 50% silver and later even less. From the mid-16th century, groschen had already become relatively worthless and when a new coin was introduced – the silver tolar. The exchange rate of both coins was then set at 30 groschen for 1 tolar.. Overseas discoveries caused a huge inflation of gold and silver and the purchasing power of groschens quickly fell. The minting of groschens ended completely with the monetary reform in 1644.
