U+10175 "𐅵" Greek One Half Sign Unicode Character

U+10175 "𐅵" Greek One Half Sign is a numeral symbol used in ancient Greek acrophonic numeration, a system where numbers were represented by the first letter of their name. This specific character denotes the value of one half and was employed in inscriptions and documents from classical Athens, particularly on stone or pottery, as part of a larger system that included signs for fractions and larger denominations. Unlike the more common alphabetic Greek numerals, acrophonic signs like this one were distinct symbols based on the initial letters of number words, with this half sign derived from the word for "half" (ἥμισυ).
