For the minting of the present coin, the classical reverse stamp of the so-called "shallow" and the obverse stamp with a doubled date, which has not yet been described in the literature, were used. The obverse stamp was made from a patrix, which has been preserved to our time by date striking. On the market, the error of stamping the date doubled with a shift to the right is known on very rare specimens of the Banner stamped with a "deep" stamp, as well as an equally rare and sought-after hybrid of the same obverse and reverse stamped with a shallow stamp. The present piece was struck using a different stamp with a date stamping error in the form of an offset to the left (and not to the left as on the described variant).
Thus, this is a new variant of the stamp, not previously described in specialized catalogs.
The denomination was introduced with the reform of January 11, 1924. Coin minted to commemorate the 100th anniversary of the outbreak of the November Uprising by decree of the Treasury Minister on November 14, 1930. Remaining in circulation until November 1939.
The coin was minted in Warsaw in an edition of 1,000,000 pieces, and was the first commemorative coin introduced into circulation in the Second Republic. It is also the only circulation coin from the Second Republic that does not have the issuer's name: 'THE REPUBLIC OF POLAND'.
