Coins from Era of Biblical Joseph Found in Egypt

“The researchers discovered the coins when they sifted through thousands of small archeological artifacts stored in [the vaults of] the Museum of Egypt. [Initially] they took them for charms, but a thorough examination revealed that the coins bore the year in which they were minted and their value, or effigies of the pharaohs [who ruled] at the time of their minting. Some of the coins are from the time when Joseph lived in Egypt, and bear his name and portrait.

“There used to be a misconception that trade [in Ancient Egypt] was conducted through barter, and that Egyptian wheat, for example, was traded for other goods. But surprisingly, Koranic verses indicate clearly that coins were used in Egypt in the time of Joseph.

“Research team head Dr. Sa’id Muhammad Thabet said that during his archeological research on the Prophet Joseph, he had discovered in the vaults of the [Egyptian] Antiquities Authority and of the National Museum many charms from various eras before and after the period of Joseph, including one that bore his effigy as the minister of the treasury in the Egyptian pharaoh’s court…

“Dr. Sa’id Thabet added that he had examined the sarcophagi of many pharaohs in search of coins used as charms or ornaments, and that he had indeed found such ancient Egyptian coins. This [find] prompted researchers to seek and find Koranic verses that speak of coins used in ancient Egypt, [such as]: ‘And they sold him [i.e. Joseph] for a low price, a number of silver coins; and they attached no value to him. [Koran 12:20].’ [Also,] Qarun [2] says about his money: ‘This has been given to me because of a certain knowledge which I have [Koran 28: 78].’”

They should have also consulted the Word of God, the Bible:

Ge 43:18 And the men were afraid, because they were brought into Joseph’s house; and they said, Because of the money that was returned in our sacks at the first time are we brought in; that he may seek occasion against us, and fall upon us, and take us for bondmen, and our asses.

The chapter 47 references also provide insight into why many in Egypt might have gone to a barter system for a time.
