Banknote 20 guilders 1937 of the Free City of Danzig, K/A series.
WMG guilder denominations, these are exceptionally prized and sought after banknotes by collectors, their printing on behalf of the Senate of the Free City of Danzig was entrusted to British printers.
A decent piece, of not bad appearance, with a PMG grading note appropriate to its state of preservation.
