I guarantee that if you try to board a commercial flight with $100k worth of gold, questions will be asked.

Current price of gold is $43/gram. Let's call that $40 to be conservative and make the math easy. So $100,000 in gold is 2.5 kilograms, a little over 5.5 pounds.

Gold is 19.3 grams per cubic centimeter, so 2.5 kilos of gold occupies a little less than 130 cubic centimeters. Therefore $100k of gold fits into a box a little smaller than 7.2 cm on both sides and 2.54 cm deep (less than 3 inches on a side and an inch deep).

If I were working for Dr Evil and was tasked with commercially transporting gold, I'd want to do some testing on what gold looked like on an Xray machine vs aluminum or steel, but feel fairly confident I could hide that small of an amount of material from anything less than a disassembly inspection.

Or just charter a private jet and take a million or two in a suitcase.

Gold appears opaque on an airport x-ray, and opaque blocks get your luggage opened and hand-checked - as would (e.g.) a gold-lined suitcase. Your box is big enough to be worth a manual check, and most countries (USA included) require you to declare high value items if you're crossing an international border, which would cover your gold box.

Fundamentally, the state is well aware of the risks of gold smuggling, and already knows how to catch it for any commercially viable amount - you'd have to carry under $10k at a time to even have a chance of slipping the net.

Gold is totally opaque to x-rays, which is very unusual, so it appears completely black on airport scanners. Thus, I hope you're not flying to/from the US, lest you end up dealing with TSA agents of the same breed that held up a guy for bringing his Nobel Prize medal through.

Solid gold, sure. But what about a wad of gold thread, or a gold-based aerogel, or thin perforated plates? One of gold's useful properties is the wide range of shapes it can be formed into, and at least some of those shapes should allow some x-rays through—perhaps enough to make it look less suspicious on the scanner.

I think it'd still show up. But it seems to be easy enough to "hide" it along the structural support of your carry on and such.

Which brings us very neatly to the other witty anecdote about mischief with Nobel Prizes: György de Hevesy dissolved a pair of Nobel Prize medals into a flask of aqua regia so that they wouldn't be stolen by the Nazis, and then precipitated the gold out of the solution after the War so that the Nobel committee could re-cast the medals.

I suppose you could try similar thing if you could find a shampoo bottle or some other inconspicuous container, that would not itself be dissolved by aqua regia---as long as you remember not to bathe in it after you land.

It would still be opaque to X-rays

This would probably fall foul of the ban on large amounts of liquids that is in force for hand luggage. That is, if you disregard the fact that aqua regia is bright orange in colour and emits fumes, which would make it very conspicuous anywhere outside of a chemistry lab (you could probably put an Irn-Bru label on the bottle to make the colour believable but you should make sure no Scots get near – they might drink from it).

No airline will let you take dangerous chemicals on board, anyway. And it's not really good for the gold, either.

So alloy it with titanium or aluminum and use it to cast one of the "metallic" luggage bags: https://www.amazon.com/Goplus-Aluminum-Suitcase-Briefcase...

Extra X-Ray thickness will not be noticeable because gold will be spread over a large surface area. Extra weight will also be hard to detect.

It's like you guys never smuggled gold, rare earths and plutonium into the United States.
