Watch List notes:

RUSSIAN COINS AND HISTORICAL MEDALS, USSR, Obverse and Reverse die for 1931 1 Kopeck. Number '62' in white on side of obverse, and '76' in white on the reverse. Extremely rare; other than a die pair for a 1924 Rouble in the Stack's August 2014 Sale which sold for a handsome $14,000, this is the only other pair of Soviet dies to be offered in auction. Very well preserved

Estimate: $4,000
