U+10157 "π " Greek Acrophonic Attic Ten Mnas Unicode Character
U+10157 "π " Greek Acrophonic Attic Ten Mnas is an ancient numerical symbol used in classical Athens, representing a value of ten mnas, where a mna (or mina) was a unit of currency and weight equal to 100 drachmas in the Attic system. This character belongs to the Ancient Greek Numbers block and is a testament to the acrophonic system, in which numerals were derived from the first letter of the word for the number, with "π " originating from the Greek word "μναΎΆ" (mna) and its initial letter mu (Μ). It would have been inscribed on official weights, currency tokens, or financial records to denote a standardized sum, reflecting the economic and administrative practices of 5th and 4th century BCE Athens. Today, its inclusion in Unicode allows for the accurate digital representation and preservation of this historical notation.
