This coin was apparently produced during the reign of Ivan IV (1530-1584) better known as Ivan the Terrible. Ivan IV was the first Russian ruler who was formally crowned as Czar (1547). Ivan the Terrible reformed the Government and Court, conquered Kazan Khan (1552) and Astrakhan Khan (1556) and created an empire that included non-Slav states. The home policy of Ivan the Terrible was accompanied by repressions and the enslaving of peasants.
