In traditional Monopoly, each player begins with $1,500. This consists of two $500 bills, two $100 bills, two $50s, six $20s, five $10s, five $5s and five $1s. The rest of the money is kept in the Bank until needed.
As players pass over the starting point -- the GO space -- they receive an extra $200 from the bank. During the game, players must pay the bank penalties such as income tax and jail fines. The Bank also receives payment when properties are purchased from it and houses or hotels are built. Buildings are sold back to the Bank at half their original prices.
