noun
bullion
BULL-yun/ˈbʊliən/
Gold or silver in bulk, especially as bars or ingots.

Etymology
Billon named a bar of precious metal, connecting bullion with metal in bulk rather than finished coins. Its history also reflects influence from a word meaning “boil,” through the notion of melting.
In context
Gold and silver were looted en masse, melted down into bullion to fill the coffers of the Spanish crown.
