25 000 Roubles The History of Russian Currency

Issued as part of a multi-coin series commemorating the history of Russian currency, this is among the largest gold coins ever produced by the Goznak mint — the 3-kilogram weight alone places it in a category occupied by fewer than a handful of Russian issues. The series drew on monetary history stretching from early medieval grivna ingots through Soviet-era coinage, requiring Goznak's engravers to compress centuries of numismatic evolution into a single format.

Mintage was extremely limited, as production at this scale is constrained more by refinery capacity and die durability than by demand.
