Very attractive and rare 3-segment (3-digit) numbering on thalers. Mariusz Kozłowski in his publication "Tickets of the Duchy of Warsaw 1810" (Zielona Góra 2025) noted a total of 625 thalers of all denominations, including only 11 pieces with 3-segment numbering(1.76% of the population).
Dark stain centrally and two lighter iron stains at the top. Technical state of preservation of the paper good, with no deep tears, only minor edge weakness.
A rare and missing denomination in many collections.
