It's a safe bet that whoever replaces Ben Bernanke as Fed chief will be personally familiar with large sums of money. Janet Yellen has assets worth between $4.8 million and $13.2 million—including a stamp collection worth up to $50,000—while fellow frontrunner Larry Summers clocks in between $7.9 million and $31.7 million, reports the Wall Street Journal. Newly released disclosure forms also show that all seven people on the Federal Reserve Board of Governors qualify as millionaires, notes CNNMoney. (Summers isn't on the board, but he had to issue a disclosure form when he worked in the White House.)
