The 1928 10 zloty is a banknote that was never put into circulation. It survived only in the form of pieces from the initial presentation batch or proof prints showing the way to the final design. Here is one of them.
It's a color sample in green-red-brown tones. It's made on the right paper, with a watermark, at 1:1 scale, uncut to final size - the wider margins where the printing stripes are visible are preserved.
A printer's deletion in place of the watermark, although the watermark is consistent with the final version.
A rare value.
