    "US bills ($1, $2, $5, $10, $20, $50, $100) and coins (1¢, 5¢, 10¢, 25¢, 50¢, $1). Counts are whole numbers from 0 to 10,000,000.",
    "Weights are nominal: about 1 g a bill (BEP) and the US Mint standard weight of each coin; worn coins weigh a little less.",
    "A deposit below $0 means the cash is short of the float. The weight in pounds uses 1 lb = 453.59237 g."
