$10 voucher 1969 MODEL, ser. Ef - zero numbering
The rarest variation of the 1969 voucher issue pattern, the so-called proper pattern, not a reworking from circulating banknotes. Oblique printing of MODEL on the obverse, perforation MODEL and zero numbering: 0000000.
A very nice piece, confirmed by a solid PMG grading note, with a typical feature of these pattern types - small staple holes on the left margin and traces of rust, as noted in the description on the slab.
