Those 'Gold bars' look more brown than yellow. Gold is chemically very stable. It does not easily combine with other substances and, therefore, does not corrode or tarnish. Maybe Egypt double crossed him with gold plated tungsten bars?
If the tungsten bars were plated with gold, they would look just as golden as a pure gold bar. I don't know if its the casting method and/or the purity of the gold but some gold bars do look like that.
