 In the coinage reform of 1700 they reappeared as much larger copper coins, and mintage continued, off and on, until 1916, just before the Romanov dynasty ended in 1917.Coins minted in the 18th century invariably showed the denomination as Denga, but during parts of the 19th century this was replaced by the word Denezhka, the diminutive form of Denga.Later still the denomination was shown simply as ½ Kopek.
