(Russian, kopeika), a Russian small change coin, equivalent to 1/100 of a ruble. It was first coined in the 1530’s from silver. During the 16th and 17th centuries it was commonly known as a novgorodka. In 1704, Peter I introduced the copper kopek into circulation, and from 1718 on silver kopeks were no longer minted. Today in the USSR the kopek is made out of a yellow copper-zinc alloy.
