Rare, the only replacement series for the 5 zloty denomination.
The notation of the series (small LARGE letter) visually coincides with the notation of the variety to which it belongs, e.g. aE, etc. (Mił.114b) but within that variety all begin with a small letter "a". The present one begins with the letter "x" and only one series xA is known.
Beautiful state of preservation with a good grade of PMG 63 EPQ.
