One of the oldest existing estimates regarding only Vault B, which can be considered to be at least as reliable as any other made since the discovery of the hidden treasure (or assets) of the Temple in 2011, was by the Travancore Royal Family itself in the 1880s (when an older existing inventory and estimate were last updated). According to it, the gold and precious stones contained in Vault B, which is by far the largest and the only vault (of the reported six) that is unopened so far, since the discovery of the treasure, was worth INR 12,000 Crores in the then (1880s') terms. Considering the subsequent inflation of the rupee and the increase in the prices of gold and precious stones since in general, the treasure in the unopened vault B alone would be worth at least US$ One Trillion in July 2011 terms, without the cultural value being factored in. The price of gold in the 1880s, when the inventory and estimate were last updated, was INR 1.8 per gram (The price of gold was about US$18 for an ounce in the 1880s when the dollar was 3.3 to the rupee).https://nma.org/wp-content/uploads/2016/09/historic_gold_prices_1833_pres.pdf In fact, going by these figures, the gold in Vault B could potentially run into many more trillions of dollars even before the cultural or historical value is factored in.
