RR-, Kingdom of Poland, 10 groszy 1830 KG, lowest mintage

A rare mintage valued at 2 zlotys in Berezovsky (higher than the 1818-1822 Alexander zlotys). The lowest mintage for a 10-penny coin, only 145,000 pieces, which for a small coin is a negligible issue, considering that all 10-penny coins were minted over 22 million. In comparison, in 1828 10-penny coins were minted 3 times more (over half a million), and in 1831 30 times more (over 4.5 million pieces). Despite the shallow minting and the late-phase print of the stamp, a nice piece shines in the background.
