Question

What were Egyptians buried with them to prove their wealth?

Answer 1

Those with more wealth would be able to afford a better burial. The graves of some craftsmen and workers have been found containing a mummified body as well as bread, fruit, amulets and furniture for the afterlife. Nobles and very wealthy people were often buried in tombs that we call 'mastabas'.

Answer 2

Oftentimes, it would be their most valuable possessions. However, as all should know, the most important and wealthiest often had entire sarcophaguses to themselves.
