The cent sign is commonly a simple minuscule (lower case) letter c. In North America, the c is crossed by a diagonal or vertical stroke (depending on typeface), yielding the character ¢.
The cent may be represented by the cent sign, written in various ways according to the national convention and font choice. Most commonly seen forms are a minuscule letterc crossed by a diagonal stroke, a vertical line, a simple c, depending on the currency (see below). Cent amounts from 1 to 99 can be represented as one or two digits followed by the appropriate abbreviation (2¢, 5c, 75¢, 99c), or as a subdivision of the base unit ($0.75, €0.99). In some countries, longer abbreviations like "ct." are used. Languages that use other alphabets have their own abbreviations and conventions.
The cent symbol has largely fallen into disuse since the mid-20th century as inflation has resulted in very few things being priced in cents in any currency. It was included on US typewriter keyboards, but has not been adopted on computers.[2]
North American cent sign
The cent sign appeared as the shift of the 6 keys on American manual typewriters, but the freestanding circumflex on computer keyboards has taken over that position. The character (offset 162) can still be created in most common code pages, including Unicode and Windows-1252:
On DOS- or Windows-based computers with a numeric keypad, Alt can be held while typing 0162 or 155 on the keypad. See Unicode input § In Microsoft Windows for techniques involving the hexadecimal code pointA2 that can be used when there is no numeric keypad, as on many laptops. For the US International keyboard Right Alt⇧ ShiftC can be typed.
On Mac systems, ⌥ Option can be held and 4 on the number row pressed.
On Unix/Linux systems with a compose key, Compose+|+C and Compose+/+C are typical sequences.
Orthography
When written in English and Mexican Spanish, the cent sign (¢ or c) follows the amount (with no space between)—for example, 2¢ and $0.02, or 2c and €0.02. Conventions in other languages may vary.
Examples of currencies around the world featuring centesimal (1⁄100) units called cent, or related words from the same root such as céntimo, centésimo, centavo or sen, are:
Euro – the coins bear the text "euro cent". Greek coins have ΛΕΠΤΟ ("lepto") on the obverse of the one-cent coin and ΛΕΠΤΑ ("lepta") on the obverse of the others. The actual usage varies depending on the language.
Guyanese dollar, but there are no circulating coins with a value below one dollar.
Hong Kong dollar, but all circulating coins are in multiples of 10 cents.
Indonesian rupiah (as sen; last coin minted was 50 cents in 1961, last cents printed as banknotes in 1964 which were demonetized in 1996 save for the 1 cent)
Jamaican dollar, but there are no circulating coins with a value below one dollar.
