100 Zlotys Władyslaw Reymont date on the right, Trial Strike

Reymont received the Nobel Prize in Literature in 1924, the only Polish writer to do so until Wisława Szymborska in 1996. This trial strike — known in Polish numismatic literature as a próba — was produced to test design placement and die alignment before the circulating issue was approved, which accounts for the variant date positioning noted in the Fischer and ParM references. The National Bank of Poland issued numerous such probes throughout the 1970s, many in nickel rather than the final circulation alloy, making compositional differences the primary distinguishing factor between trial and regular strikes.
