Poland's postwar coinage underwent several aborted redesigns during the late 1950s as the government weighed both aesthetic and material options. This nickel trial was part of that process — the "Pigeons" design was ultimately rejected for the circulating 1 Złoty, which instead carried forward a different motif. Trial strikes of this type were produced in extremely limited numbers for internal evaluation and never entered commerce, which is why surviving examples almost always appear in exceptional condition by default rather than by luck.
The Fischer and ParM references both catalog this as a pattern, not a proof, distinguishing it from presentation strikings made for collectors.
