U+2183 "Ↄ" Roman Numeral Reversed One Hundred is a rarely used typographic symbol that represents a mirrored or reversed form of the Roman numeral for one hundred, "C." Historically, it was employed in ancient Roman inscriptions and medieval manuscripts as a shorthand or variant numeral, sometimes appearing as a symbol for the number one hundred in certain positional numbering systems.
