A rare one-letter variety.
Banknote illustrated in Czesław Miłczak's latest two-volume catalog (issue 2023, vol. II, p. 177).
Piece repeatedly broken. After full restoration.
The banknote bears a PMG certificate with a PMG rating of 30.
An item with great investment potential, as banknotes illustrated in well-known catalogs are definitely more strongly valued abroad, which has also been noticeable in Poland for some time now.
