richer than Croesus

Very wealthy. Croesus ruled an ancient Asia Minor kingdom who amassed a fabulous amount of wealth (he is also credited with having minted the first gold coins). How he would have compared to computer moguls and hedge-fund tycoons can never be measured, but his name lived on as someone who wasn't worried about where his next meal was coming from. “Rockefeller” was the late 19th- and 20th-century comparison: “He spends money like he's Rockefeller.” A Chock Full O' Nuts commercial included the line “better coffee Rockefeller's millions can't buy” until the Rockefeller family requested a change to “better coffee a millionaire's money can't buy.”
