Golden plates found in Egyptian sarcophagus

The most interesting thing about the 2,000 to 2,300 year old tomb found 15 feet underground recently in Alexandria, Egypt, is not so much the three mummies, which water seepage had damaged, but the golden plates found with them. Despite warnings of a "curse", the huge sarcophagus yielded enough material for egyptologists to pore over in coming years. These gold plates were NOT mentioned immediately after the tomb was opened, probably because they were sunk at the bottom of a deep pool of strange, bright red liquid. But WHAT MEANING was intended, in interring these strange golden plates (one of which shows a large serpent), with the mummies? The two other plates show symbols which are even harder to describe or explain. They could be symbols from a Pharaonic religion from the time of Alexander the Great which has since completely disappeared.

I photo'd the TV screen during a short YouTube documentary and then edited the shot into the three pix you see. Some of the golden brightness was lost. I wonder if these images were thought by the ancients to offer honor or protection to the dead? No experts seem to have offered any opinions yet!
