pick #21 is orange version



Discussion about
Danzig, City of • 1 000 000 Mark
That does look like a P#21…
SC#21 is Red overprint on SC#20
SC#22 is Dark blue overprint on SC#20
Pick#21 & Pick#22 @ Banknote Museum.
Hopefully @Hibernia can verify.
I will look into this.
I looked this up in scwpm, which does not mention the overprint colour, and p21 and p22 just mention 1 Million overprint on 50,000!
Here is the numista entry.
So, we need to adjust this to reflect the two overprint colours.
The overprint colours are not listed in the Catalogue, however, in the NumisMaster database that the book was printed from the overprint colours are listed per pick number...

(P#22) 
A pity this did not make it into the catalogue - queued for the subsequent edition perhaps.
@Hibernia all polish catalogues are motion about this. Current version Czeslaw Milczak catalogue have WMG - Danzig banknotes and PMG is using this book as reference . Also previous Podczaski catalogue contain WMG banknotes and notegelds
