The Mna is a unit of measurement of mass (subdivision of talent) used in ancient years. Coins of precious metal weighing one mna, also used as currency.
First subdivision of the talent to mna does the peoples of Mesopotamia, originally represented 1/50, but later changed to 1/60. The Greeks adopted the second ratio. An Attic mna of the classical era weighed 433 grams today.
Currency divisions in ancient Greece:
- 60 Mnai worth one Talent.
- 1 Mna amounted to 100 Drachmas*.
- 1 Drachma corresponded 6 Obols.
- 1 Obol corresponded 8 Coppers.
*(Etymologically Drachma means coin that can be caught by hand, as opposed to the unwieldy mna that weighed almost a half kilo. The silver drachma was the main currency of ancient Greece.)
