c-note
Synonym discussion
Sense: noun/1
These four terms all name a $100 US banknote but differ in register and context. A hundred-dollar bill is the neutral label used in banks, news reports, and official documents. C-note is an informal, somewhat old-fashioned slang term that originated in early 20th-century jazz and gangster culture; it still appears in American movies and casual conversation. Benjamin (or Benny) is more recent slang, referencing Benjamin Franklin's portrait on the bill, and carries a slightly playful or streetwise tone. Hundred is the bare shorthand used by cashiers and in everyday talk ('That'll be two hundred' — no bill word needed). In writing a cheque or filling out a form, use hundred-dollar bill. In a casual story about paying for dinner, c-note or hundred work naturally.

Etymology
C-note is a compound of C (the Roman numeral for 100) and note (a 19th-century slang word for a banknote or piece of paper money). The term entered American slang in the early 1900s, and became especially popular in the 1920s–1940s through jazz songs, crime fiction, and film noir, where a character paying with a c-note signaled a big spender or shady deal. The prefix C- has also been used for other denominations (e.g. fin = 5-dollar bill, sawbuck = 10-dollar bill), but c-note is the only one still in common use today.
