1940 20 zlotych banknote, AB series— zero numbering: 0000000
Typical zero-series numbering; the font is characteristic of Series A designs; the Series AB overprint is executed in a different font and ink color. Most likely a test print, prepared in anticipation of the issuance of this denomination with a two-letter series (?)
A beautiful piece in excellent condition, with only slight creases and gently refreshed paper.
Featured in the Lucow collection catalog; the banknote comes with a certificate.
