50 Groszy Ear and Hammer, Trial Strike Ni

Poland's postwar coinage underwent significant redesign pressure in the late 1950s as the PZPR regime pushed for imagery more explicitly aligned with socialist iconography. The ear-and-hammer motif on this trial was part of that effort — a proposed design that never advanced to circulation. Trial strikes in nickel from this period were produced in extremely limited quantities at the Warsaw Mint solely for government approval review, making survivors genuinely scarce rather than artificially so.

The Fischer and Par reference numbers confirm this as a documented pattern, not an afterthought attribution.
