What ↂ means
The large Roman numeral ↂ represents 10,000.
The apostrophus system used marks shaped like a reversed C alongside Roman letters to write large numbers. In that system, CCIↃↃ represented 10,000; ↂ is the compact single-character form associated with it. This notation is attested by 500 AD, though it was not widely used before the Middle Ages.
Why does ↂ look different from familiar Roman numerals?
It is one of the extended forms for Roman numbers above 1,000.
Other signs in that set include ↁ for 5,000 and ↇ for 50,000. A long overline is another notation for multiplying a Roman numeral by 1,000, so X̅ can also stand for 10,000. These are distinct written forms, and their exact strokes vary by font.
