U+03E1 "ϡ" Greek Small Letter Sampi Unicode Character

U+03E1 "ϡ" Greek Small Letter Sampi is an archaic letter of the Greek alphabet that was used primarily as a numeral symbol representing the number 900, rather than as a standard alphabetic letter in classical Greek writing. Its name "sampi" is thought to derive from the phrase "like a pi" or possibly from the Greek word for "together," and its shape resembles a vertical stroke with a curved tail, which has led to its occasional confusion with the similar-looking sigma. In modern contexts, sampi is almost exclusively encountered in scholarly works on ancient Greek epigraphy and paleography, or in mathematical and numbering systems where obsolete Greek numerals are still referenced.
