Troves of Treasure is a term used to describe a large collection of valuable items, such as coins, jewelry, and other artifacts. It is often associated with pirate treasure, but can also refer to any large collection of valuable items. The term is derived from the French word 'trouve, ' which means 'FOUND.' RICHES is an appropriate six-letter synonym for Troves of Treasure, as it is a term used to describe a great abundance of wealth.
