POLAND. 20 Zlotych, 1836/4-CNB NA. St. Petersburg Mint. Nicholas I. NGC AU-58. KM-C-136.2; Bit-1077; Parchimowicz-1046. Mintage: 307. Displaying reflective qualities throughout with evident pebbly texture appearing in the reverse fields due to the usage of an old 1834 die that was reworked, the remnants of the 4 in the date remaining below the final 6 digit. While not surprising considering the extremely low mintage, a <strong>RARE</strong> date that is sure to be avidly sought by Polish collectors.
