100,000 zloty banknote , 1990 – AB series – DESTRUKT –the so-called “butterfly”
A striking printing defect, commonly known as the “butterfly”—due to an uneven excess of paper extending beyond the standard dimensions of the banknote. This defect occurs when individual banknotes are improperly trimmed from the sheet. Such banknotes should not enter circulation, which explains their current rarity and high demand among collectors.
The piece offered in this auction features an interesting variant: in the lower left corner, there is excess left and bottom margin—on which printing marks are visible.
A nice piece, confirmed by a solid GDA grading note, with an EPQ annotation attesting to the exceptional quality of the paper.
