P.34s.
Alphabet X.191 - number 034, with signature and triple perforation "SPECIMEN" vertically to the right and left of the bill, as well as horizontally in the center. It is not uncommon for certain types or countries to use banknotes as SPECIMENs. Moreover, this type is quite simply extremely rare: no sales records, never presented at auction and no bills referenced in the PMG population database to date.
Exceptional and rare, with margin marks on verso and corners (paper damaged). SUP to SUP+.
