History of Money and Exchange
📌 Initially, people met their needs through self-sufficiency (hunting, farming, making clothes) before realizing production was often insufficient.
🤝 The need to trade led to the development of the Barter System, where goods were exchanged directly for other goods.
🧂 A major drawback of barter was the difficulty in finding a mutual trade partner, leading to the use of high-value items as common exchange media, such as salt used by the Romans (the word 'salary' comes from the Latin *salarium*, meaning salt).

Evolution of Currency
🪙 Due to the perishability and inconvenience of early exchange items, metals like gold and silver were adopted because of their high value and durability.
📜 As economic transactions grew, handling large quantities of metal coins became cumbersome, resulting in the invention of paper money.
🧾 Early paper money functioned as receipts or certificates representing ownership of underlying gold or silver deposits, forming the precursor to modern banknotes.

Key Points & Insights
➡️ The primary driver for the evolution of money was the inefficiency and limitations of previous exchange methods (self-sufficiency $\rightarrow$ barter $\rightarrow$ commodity money).
➡️ The concept of a store of value and standardized medium of exchange was crucial, leading to the adoption of durable assets like precious metals.
➡️ Modern paper currency originated as a promissory note or proof of ownership over physical commodities (gold/silver).
