Nicholas I Kopeck 1851 BM MS66 Brown PCGS, Warsaw, Poland mint, Bitkin-867, KM-C149.3. A superb example of this scarce issue. The luster is full, and shimmering, beneath attractive reddish-brown patina. The strike is near-perfect and only a few insignificant spots mark this appealing piece. A conditionally rare issue, this iridescent jewel is two grades finer than any other piece certified by either PCGS, or NGC.
Estimate: 800-1000 USD
