R.S.F.S.R. silver Proof 10, 15, and 20 Kopecks 1921,
1) 10 Kopecks KM-Y80, PR66 NGC
2) 15 Kopecks KM-Y81, PR66 Cameo NGC
3) 20 Kopecks KM-Y82, PR66 Cameo NGC
A fabulous trio of 1921 Proofs, with the 10 and 20 Kopecks brilliant white and the 15 Kopecks exhibiting a touch of light russet patina. All three pieces are sharply struck, with no significant flaws and the 15 and 20 Kopecks show nice cameo contrast. It would be difficult to find a nicer group of these three 1921 Proofs.
Estimate: 6000-7000 USD
