WebKoppa (Ҁ ҁ; italics: Ҁ ҁ) is an archaic numeral character of the Cyrillic script. Its form (and modern name) are derived from some forms of the Greek letter Koppa (Ϙ ϙ). [1] [2] Koppa was used as a numeral character in the oldest Cyrillic manuscripts, representing the value 90 (exactly as its Greek ancestor did).
