electrum 2 Bu coin from Japan during the Tokugawa Shogunate era, specifically from the Edo period, in the city of Kinza (which I assume refers to Kinza mint). This coin was minted during the reign of Emperor Mutsuhito, also known as Emperor Meiji, who ruled from 1867 to 1912. The coin weighs 2.92 grams and measures approximately 19x11mm. It is described as being in VF/XF (Very Fine/Extremely Fine) condition.
The coin is known as a Meiji Ni-Bu-Ban-Kin and is cataloged under KM C#21d. This coin would have been circulated in Japan during the transitional period from the Tokugawa Shogunate to the Meiji Restoration, which marked significant political and social changes in Japanese history. 
If you are a collector or have a specific interest in Japanese numismatics, this coin could be a valuable addition to your collection due to its historical significance and unique characteristics.
