U+10167 "𐅧" Greek Acrophonic Troezenian Fifty Alternate Form Unicode Character

U+10167 "𐅧" Greek Acrophonic Troezenian Fifty Alternate Form is a numeral symbol from the ancient Greek acrophonic numeral system, specifically representing the number 50 in the Troezenian local variant. This system, used primarily in inscriptions and accounting from around the 5th century BCE, derived its symbols from the initial letters of number words, and this alternate form served as a regional variation distinct from the standard Attic or other city‑state numeral shapes. It belongs to the Ancient Greek Numbers Unicode block and is primarily of interest to historians and epigraphers studying archaic Greek numeral conventions, as it offers insight into localized numbering practices before the later adoption of the more widespread alphabetic Greek numerals.
