The development of coined money significantly changed trade by making it easier to conduct transactions and increasing the speed and volume of trade. Before the use of coined money, trade was conducted through bartering, which made transactions difficult as people had to find someone who wanted what they had to offer.
The introduction of coined money also made trade between different cultures easier, as people could use a standardized currency to buy and sell goods. This led to the growth of international trade and the exchange of goods and ideas between different regions.
However, the cost of goods did not necessarily become too high for many regions. The value of money was based on the amount of precious metals it contained, such as gold or silver. This made the cost of goods more predictable and stable, as prices could be based on the value of the currency.
Overall, the development of coined money had a significant impact on trade, making it easier, faster, and more efficient.
