The year 1853 marks a change in Japanese history. It is best known for the arrival of the "Black Ships" (Japanese: kurofune). The term was used for European sailing ships as early as the 16th century. In this case, it refers to the fleet under U.S. Commander Matthew Perry, which ended Japan's long isolationist policy. With the Meiji Restoration in 1868, the last shōgunate was finally abolished and the Empire was founded. The revolutionary phase was characterized by struggles between the supporters of the shoguns, such as their famous nobility, the samurai, and pro-imperial forces. These currency ingots – two made of silver and two of gold – date from this turbulent period.
