Coins from the Jagiellonian Era
When the layer covering the lid was removed, a group of coins poured out, including some silver denars issued under Casimir IV Jagiellon. He reigned as King of Poland and Grand Duke of Lithuania from 1447 to 1492. Subsequent analyses showed that the hoard consisted of 592 silver Jagiellonian denarii and 26 silver half-groschen struck in two diameters. It also held four gold ducats struck under Sigismund of Luxembourg, Holy Roman Emperor and King of Hungary and Bohemia (1387–1437).

Significance of the Find
The ducats were found in a newspaper bound with string, and with the utmost pains laid gently on the silver coins. Tomographic investigations revealed that this configuration was intended. "The deposit symbolises the importance of the Bochnia region as an axis of trade and economic life in the medieval period," say the experts. The ship and coins will be transported to the Stanisław Fischer Museum in Bochnia, where they will be maintained and eventually made accessible to the public.
