How do you identify money?

Money can be identified by its key characteristics: it serves as a medium of exchange, a unit of account, and a store of value. It typically comes in the form of coins, banknotes, or digital currency and is widely accepted for transactions. Additionally, money often has government backing or is recognized by a community as having value. To identify specific currency, one can look for unique features such as denominations, security elements, and issuer information.
