U.S.S.R. Proof 1, 2, and 3 Kopecks 1926,
1) 1 Kopeck KM-Y91, PR64 NGC
2) 2 Kopecks KM-Y92, PR65 NGC
3) 3 Kopecks KM-Y93, PR66 NGC
A very well matched set of these very elusive issues. The strikes are all quite bold, and the fields mirrored, with red, blue and gold patinas. An extremely rare group of Proofs and some of the very few Proofs of these issues we have seen. In our 2014 CICF auction we sold a four-piece set of the 1926 Proofs (including the 5 Kopeck) at $13,000 hammer. The prices in Krause are ridiculously low and we expect active bidding on these seldom offered pieces.
Estimate: 6000-8000 USD
