The 13.5 tons of gold had me curious. 13.5tons = 27000 lbs = 432000 oz

Gold is between $4700 to $4900 per oz

The value is between $2.03 to $2.12 billion usd

To be fair, 13.5 tons of gold is about 700 L (using a density of 19.3 kg/m3). That's a lot, sure, but still far smaller than your average cupboard.

You could literally fit this stuff under a decently sized bed (2m x 1.8m, with 20cm elevation), inside a fridge, or behind the clothes in a wardrobe.
