A set of a rare variety of designs from the first PKO SA voucher issue of 1960. Current numbering, black MODEL stamp and double perforation. Czeslaw Miłczak notes similar pieces, but with single perforation and purple stamp.
These patterns were created due to the increase in the number of Pewex stores, hence booklets were made already on circulating pieces.
Punch mark after removal from the block.
All in PMG grading, from circulating to bank states.
The highest denominations are particularly nicely preserved.
