I did the calculation as well and $130 Billion dollars worth of gold is an unreasonable amount to be on a single ship as well as an unreasonable amount for the purpose. 884,000 pounds (12 troy ounces per lb)
Unless they are applying some kind of premium value as historical relics or collectibles.
When I calculate using 12/oz per lb as opposed to 16, I get more lbs for the $130 billion: 8.84 million lbs. One of us is slipping a decimal somewhere. But the gist is: no one ship would/could be carrying that much gold.
