Bread

‘Bread’ meaning money is first cited as American slang from the 1930s, probably deriving from earlier American slang, dough, also meaning money that dates from the late 19th century. Both are thought to derive from the phrase ‘bread and butter’ which has been synonymous for a living, or earning a living, since the late 18th/early 19th century. There is also rhyming slang, bread and honey/money, but this is thought to have emerged in Britain during the 1960s, well after the American slang version had made its appearance in the 1930s.
