Republic silver Specimen Pattern 100 Zlotych 1925 SP55 PCGS, Warsaw mint, Parchimowicz-P168d, KM-Pn284, plain edge. Comparing this piece to the enlarged images of P168a and P168d in the Parchimowicz catalog, "Monety Rzeczypospolitej Polskiej 1919-1939, it is obvious that this piece is Pa68d, and not P168a as noted on the PCGS holder. An extremely rare Pattern issue commemorating Kopernik. Struck with a small mintage of only 50 pieces. Bright, and fully lustrous, with no significant flaws.
Estimate: 6000-8000 USD
