Bank Polski suspended normal coin production well before the German invasion of September 1939, but trial and pattern strikes from 1938 document the bank's planning for a revised coinage series that never entered circulation. This particular trial omits the flanking oak leaves found on the adopted design — a deliberate variant struck to evaluate compositional options rather than a production error. The P44.1 designation places it firmly in pattern territory, meaning it was never intended for release and surviving examples almost certainly came through institutional channels rather than circulation.
