The 1994 Polish specimen series documents every stage of the Thomas De La Rue production process for the National Bank of Poland—from final approval to official distribution and archival retention. Each version was printed from the same live plates and carries the same prefix and numbering format, allowing the entire chain to be reconstructed for the first time.
Production began with the unmarked Wzór akceptacyjny bez nadruków (here referenced as barebone / Wc*)—a complete, fully signed approval print without overprint, stamp, or perforation. Once accepted, two marked forms followed: the Polish Wzór z nadrukiem WZÓR (Wa) prepared by PWPW for domestic reference, and the London De La Rue Specimen with red SPECIMEN overprint and red NO VALUE stamp (Wb) printed for international distribution. A final archival group was perforated SPECIMEN OF NO VALUE (Wd) as permanently cancelled reference copies.
The AA prefix (100 zł) forms the core of the 1994 specimen record, showing the complete four-type sequence. Miłczak’s 2023 catalog lists the first three of these forms but omits the perforated SPECIMEN OF NO VALUE type. That final stage begins the expansion beyond the printed record and opens the path to what follows.
Additional prefixes confirm that De La Rue and PWPW repeated the same production cycle beyond the initial AA run. The AP prefix examples presented below are drawn from the same 100 zł denomination and demonstrate how the identical approval–distribution–archive pattern continued through subsequent batches.
The AP prefix examples serve as one representative extension of the 1994 production chain. Their presence confirms that De La Rue applied the same four-type workflow across multiple prefixes and denominations. Other prefixes such as AF, AR, BQ, BS and several additional runs display the same pattern of approval, red overprint, and perforation. None of these have appeared in printed references to date; they are recorded here directly from surviving production material held and documented by 1994.pl.
Together, the AA and AP examples complete the view of the 1994 issue as a unified project — one that bridged Polish domestic production with De La Rue’s international specimen standards. This record does not challenge earlier publications; it expands them, grounding the printed framework in firsthand evidence.
