"Exchange Value" (1981) is a short story by American writer Charles R. Johnson. Set in Chicago, where Johnson himself lived for a time, this story addresses the corrupting power of money and wealth, and the problem of "hoarding", which is accumulating food, money, and other things for future use, as two brothers steal from a deceased woman, whose outward signs of poverty and begging belied her true nature: a rich, yet cheap, woman who hid her wealth away.
