RRR- 5 gold 1930, HYBRYDA, obverse DEAD SCANDAR, not catalogued

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 a DEEP BANDAR with a date offset - DOUBLE DATE (as on the deep banner exhibited at WDA-MiM17/498 https://wda.onebid.pl/pl/monety-rrr-5-zlotych-1930-gleboki-sztandar-niekatalogowany/346326 - where we described how the stamp was created) were assembled, while a stamp typical for minting circulating coins was used to strike the reverse. An extremely rare coin, so far undescribed, definitely rarer than the deep banner. An excellent piece with a very high grading. Piece with additional DOUBLE DIE inscription "GOLD" and serrations at the rim. A COIN FOR THE BEST COLLECTIONS.
