If you image search "gold bar" you'll find a lot of images other than the stereotypical large "Good Delivery" (400 troy oz ~12.4 kilos, Wikipedia has more details on the Good Delivery specifications). Apparently 1000g bars ("Kilobars") are common for trading, but there are images of "Credit Suisse" 100g bars that turn up as well.

Right, though given 342 "bars" are mentioned, market price of gold is known, and that in sum the bars were worth $2 million USD - it's possible to try to get a feel for if the weight and worth of gold "adds" up in logically.

See my response to a comment on the same level as your comment for my attempt to look at the numbers.
