King Tut's spectacular golden treasures harbor secrets, some invisible to even the most expert eye, until now.

Of all the 5,398 treasures from the tomb of Tutankhamun now being assembled and forensically investigated, it's the ones that paint a picture of Tutankhamun's family that are the most unsettling.

King Tut's incredible death mask -- 24 pounds of pure gold -- has always been the subject of debate with many scholars believing its damaged nameplate, known as a cartouche, and different colors of gold meant it was never made specifically for him. It was more likely made for his female ancestor, Nefertiti. And, until now, the evidence seems to back that theory up. New analysis of some of his many burial goods, including Shabtis -- miniature effigies that were meant to act as servants in the afterlife -- suggest up to a quarter of all the treasures in the tomb were made for someone else.

Howard Carter's discovery of Tutankhamun's tomb in 1922 made headlines across the world, sparking a global frenzy for Ancient Egypt. But over the decades since the find, many of the pharaoh's priceless grave goods have disappeared into museum basements and archives across Egypt. Now all 5,398 objects are reunited for the first time at the new Grand Egyptian Museum in Cairo.
