There was a period in the Early Middle Ages when very few coins were produced, and the presumption is that during this period economies of Europe were dominated by barter, though there is no record of this. We know that a stable currency was introduced by Charlemagne with the Frankish denier, which was intended to reestablish the Roman denarius as a monetary basis. The denier was adopted by a large number of other countries, including the Ango-Saxon kingdoms, where the new penny was of very similar value.
Money Economy
-----
This question assumes a state of affairs that might not have existed - that the economy at some point of the Middle Ages was based on barter. We really do not have evidence that this is the case. What we do have evidence of is a diminished quantity of coinage, and a lack of standardization of coinage, both of which happened at other times, including in the ancient Roman Empire.
There is a link below to a list of Frankish kings. There are pictures in the list of several coins, the earliest of which was made only a few decades after the fall of the West Roman Empire in 476, its style is clearly that of a Roman Emperor of the 5th century. The article shows nine or ten other coins of Frankish kings of the 6th and 7th centuries.
Other Germanic groups also used coinage extensively, as can be seen with the links to images of coins of Visigoth, Lombard, Ostrogoth and Vandal kings of the 5th, 6th, and 7th centuries.
In the 8th century, Charlemagne standardized the currency of much of Western Europe. The coin he introduced was the denier, a copy of the Roman denarius. It was ancestral to the French denier, British penny, German pfennig, Portuguese dinheiro, and others.
An economic system that replaced barter is the use of money. This money is backed up by the countries gold.
The key element from a market economy that has replaced the barter system would be affiliate marketing. This is a performance-based form of marketing.
Most commerce now depends upon the exchange of money for goods and services, rather than the exchange of goods and services for other goods and services.
The issuance of money replaced the barter system.

The native barter system is the barter system of the natives. I know this, because I am a native, and I barter pigs. I enjoy bartering and wish to do so until the day of my death, which is scheduled for Deccember 6th, 2024.
