I was thinking that by 1992, all of the Soviet related themes would have been removed. By then currency deflation occured and 10 rubles is minted in a smaller planchet (similar to the 1991 1 ruble planchet but different edge) with the double headed eagle on the reverse. A few 10 rubles of such escaped from Leningrad mint I guess.
