Polushka

A polushka (Russian: полушка) was a Russian coin with a value of 1/4 kopek. It was the smallest denomination coin issued in Russia for much of its history. The name derives from the word "pol" (пол), meaning "half," referring to it being half of a denga (another small Russian coin).

Polushkas were minted from the 15th century until the mid-19th century, with varying designs and metal compositions (typically copper). Their small value meant they were often used for small transactions and were associated with poverty.

The production of polushkas was eventually discontinued due to inflation and the increasing cost of production relative to their low value. The coin became largely obsolete by the 1860s.
