The trojak, with which began the history of the denomination, which in subsequent years conquered Europe.
The first trojak, and also the first Polish crown coin to feature a modern portrait of the king.
A large, striking issue with a diameter of almost 30 mm (Sigismund III's trojak was a mere 20 mm), whose creation was the result of Poland's struggle against the "sub-value" Świdnica half-penny issue.
On October 15, 1526, after almost 10 years of unsuccessful struggle to withdraw the coins of Ludwig (nephew of Sigismund I) flooding Poland, a new minting ordinance is introduced. Among the coins previously issued (such as denars and pennies), types of coins previously unknown in Polish minting are introduced, including the three-grosz coin.
The bullion for their minting was decided to be obtained from melted down Świdnica half-pennies. The triprockets, according to the minting ordinance, were to contain 2.32 grams of pure silver. The use of low proof silver (a mere 6-ounce sample), made the coins relatively large in size.
Very rare.
Few pieces of this distinctive issue have survived to this day, due to both the low-quality bullion being very susceptible to oxidation and Copernicus' law (inferior money drives out superior money).
