A Small Goof...or Two...
In one of the scenes near the beginning of the film, when Sinuhe, Horomheb, and Kapta are drinking in the Inn where Merit works, Horemheb suggests that he take Sinuhe out at dawn to hunt lions.
Sinuhe then stands up, and removes a leather pouch from his robe. He pulls two coins from the pouch (you can hear them clinking together) and drops them onto the table, with the words to Merit "To pay our score..."
Similarly, later in the film, when Sinuhe has set himself up as a Physcian, just before he re-meets the now-diseased Nefer, Kapta states that he even had to "return the coppers" that he had collected for appointments with Sinuhe.
The fact is that the Ancient Egyptians never had currency in the form of coins - copper or otherwise, as we do today. All their trade was by barter, or exchange of goods or services...
Similarly, the field and trade workers were paid in bread, beer, grain, or lodgings.
Coins were finally introduced by the Greek invaders about 300BC.
Thank You.
