(n.)
Slang.
A C-note is one of a handful of colloquial terms for the one-hundred-dollar bill, “C” being the Roman numeral for “100” (from the Latin centum, meaning “one hundred”). Starting after the Civil War, United States Notes of the $100 denomination featured a capital “C” on the front. Federal Reserve Notes, introduced in 1914, did away with the letter.
It is perhaps more old-fashioned than other slang terms, like “Benjamin“.
