Used example, genuine and correctly attributed. The gold print is well preserved, with clear relief and sharp engraved lines; ornamental details and the central figure of Helvetia remain fully legible, without significant rubbing or loss of print. Colour is even, with no major thinning of the gold impression. Printed on fibrous paper, consistent with the listed variety; fibres are clearly visible under magnification and in backlight. Reverse without gum, as expected for a used stamp, showing a light postal marking impression and natural age-related toning; no signs of chemical cleaning. Perforation is generally sound and regular, with a minor fault: a small nick/partial loss to one tooth at the top edge. This defect is limited and does not affect the frame or overall visual appearance of the stamp. All other perforation teeth are intact and well formed. Partial cancellation present, unobtrusive and not detracting from the design or denomination. Overall condition: very fine for this scarce high-value classic issue; the minor perforation defect is noted but does not materially detract from the stamp’s collectability or strong catalogue value.
