Large-scale counterfeiting of base silver coins of the Polish-Lithuanian state in the seventeenth century, using the technology of minting machines which were modern in those times, makes it possible to attempt a relatively precise identification of counterfeiting workshops. The article is an attempt to inventory and determine the place of production of milled false shillings of Sigismund III (1587–1632) and John Casimir (1648–1668) preserved in collections.

In 1972 a seventeenth century wooden church has been moved from Bączal Dolny to an open-air museum. Over 30 coins dating back to a period ranging between the middle seventeenth century and the middle twentieth century have been found in thxe place where the church used to be located. Lack of older coins proves that if there was another church in this area before the 1600s, it could not have been erected on the same spot.
