Bank Polski commissioned trial strikes for the 1932 zloty redesign as part of a broader effort to rationalize the coinage following Poland's adherence to the Gold Exchange Standard in the late 1920s. The "2x próba" designation indicates a second-pattern trial — meaning at least one earlier striking was rejected before this composition and specification were tested. Pattern and trial pieces from Bank Polski during this period were struck in extremely limited numbers, almost entirely for internal evaluation and ministerial approval, and rarely escaped institutional hands.
