The following development of money have therefore been the use of, except______
Answer Details
The option that has not been a development of money is "Abacus". An abacus is a counting tool used for arithmetic calculations, and it was used before the invention of money. It was used to keep track of quantities of goods, but it was not used as a form of currency or exchange.
Coins, inconvertible paper money, and commodities, on the other hand, have been used as forms of money. Coins are pieces of metal with a specific value stamped on them, which were used as a medium of exchange. Inconvertible paper money is paper currency that is not backed by a commodity such as gold or silver, but is used as a medium of exchange based on trust in the issuing government. Commodities, such as gold, silver, or cattle, have also been used as money because they have value and can be traded for goods and services.
