Revolutionary 5 Zlotych 1831-KG MS64 NGC, Warsaw mint, KM-C124. Struck during the Polish uprising, this one-year type features exquisite surfaces in argent-gray with champagne and aquamarine iridescent highlights that cling to the devices. With a mintage of just 22,571 pieces, this issue is typically encountered in low grades, which makes this near-gem an outstanding representative of the type and one worthy of a strong premium.
