Odd Denomination - 3

3 is an uncommon denomination in banknotes - most of the world sticks to 1-2-5-10 denomination banknotes. Notes of 3 denomination are unusually common in communist countries - which were a part of the former Soviet bloc, including the USSR, Bulgaria, and Cuba. Even after the fall of the Soviet Union, former Soviet Republics such as Georgia, Kazakhstan, and Tajikistan continued to issue banknotes in this denomination for some time. The denomination made sense in the communist era - where all prices were set by the government, and many everyday items were priced in multiples of 3. While the denomination has practically died out today, these notes are a window to a time when the world was structured differently.
