From Archeologists find 'Joseph-era' coins in Egypt
"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," said the report."
