List of missing treasure in the context of "Treasure"

Treasure (from Latin: thesaurus from Greek θησαυρός thēsauros, "treasure store") is a concentration of wealth — often originating from ancient history — that is considered lost and/or forgotten until rediscovered. Some jurisdictions legally define what constitutes treasure, such as in the British Treasure Act 1996.

The phrase "blood and treasure" has been used to refer to the human and monetary costs associated with massive endeavours such as war that expend both.
