What is used as money

Money is anything commonly used and accepted as a medium of exchange. Money is the evidence that the possessor has parted with commodities or services and has not yet received its equivalent. Therefore, in the final analysis, money may be any object (paper, metal, beads) used as the receipt or acknowledgment of delivery of goods or services having exchange value, as long as it is recognized as such by its users and those by whose sovereign power it was created.
