It begins to be difficult to describe a group of such stunning 10, 15, and 20 Kopeck Proofs. This is the last of our incredible three-piece lots. As with the previous lots, this group is boldly stuck, with deeply mirrored fields, as one might expect. The 10 Kopecks exhibits reddish-gold toning, with blue highlights. The 15 Kopecks has similar color, bur slightly less intense and the 20 Kopecks displays silver-gray toning with blue highlights. No 1925 Proof coins, of these three issues, has been certified higher than 66 by NGC.
Estimate: 10000-12000 USD
