U.S.S.R. copper-nickel Pattern 2 Roubles 1958 MS63 PCGS, KM-YA134. Lustrous and well struck, with a light golden tint. As with the 5 Roubles that follows, these pieces were struck as circulation coins, then all but a very small number were melted and a tiny number somehow escaped the mint. Very rare, and the only piece certified by PCGS and NGC.
Estimate: 3000-3500 USD
