It would seem that the minting of coins of the Second Republic has already been completely researched and described. However, it turns out that it is still possible to discover something new. An uncatalogued hybrid, where the stamps used for minting the DEEP BANNER with the date minting offset - DOUBLE DATE (as on the deep banner once exhibited here
https://onebid.pl/pl/auction/604/lot/498/rrr-5-zlotych-1930-gleboki-sztandar-niekatalogowany ) were assembled for minting the reverse, while a stamp typical for minting circulating coins was used for minting the reverse. An extremely rare coin for the BEST COLLECTION.
