Sure, but would it still be enough to make converting, transporting, and converting it back to purer gold economically viable? I mean by that logic you could also have a couple of mules wear expensive jewelry or watches or the like; if it's convincing enough that someone wears a $500K watch as personal effect then they wouldn't be flagged for inspection. In theory anyway, I don't know how these things work in reality. I wonder if someone's financial status is pulled up at passport control. I don't believe it's uncommon for rich people to travel coach though.
