Final answer:
The coffin that Agatha was trapped inside before Hester broke her out was made of turquoise and the inner coffin was made of solid gold.
Step-by-step explanation:
The coffin that Agatha was trapped inside before Hester broke her out was made of turquoise. However, the inner coffin was made of solid gold. When Howard Carter discovered the coffin, it was covered in a thick black pitch-like layer, which was likely an anointing liquid poured over the coffin during the burial ceremony. The outer coffin may have decayed, but the inner coffin made of gold still remained.
