In regards to “a brief history of money”, I also consider the Bible as a reliable record of history, which includes plenty examples of barters (cedar in exchange for wheat and oil), monetary designations (silver coins -gerah, shekel, minah, talents), money brokers/dealers (kermatistes in greek), payment scales (to convert monetary metals), head tax, inflation (dishonest weighing of commodities such as grains in order to squeeze more silver shekels from the people) and protests, etc…
For those questioning the barter system, livestock was often figured in barter as a medium of exchange. The latin word for money is drawn from pecus, meaning “cattle”. The usual Hebrew term rendered money means silver.
