Funny story, my father used to work down the docks here many years ago. There are some amazing stories that come out of a working port if you know the type.
Gold bullion came in, and as cinema rarely shows, gold bars weigh a lot. So you'd basically have a wooden palette holding three bars. The dockies had to pick up a palette and transfer it to the rail car next to the offloading area. The usual armed security there with the ticking and counting of all bars at each stage of transport.
Dockies being dockies, they weren't carefully setting things down when it was that much effort, to if they could, they'd basically do a swing and drop rather than carry and carefully settle into place.
Everything is accounted for, onloaded onto the rail car. Security onboards around it, and it gets shunted off to a different area of the docks. The dockies start to move onto the next job. When suddenly, someone spots in the middle of the tracks, a lone gold bar. Guessing there was a hole in the rail car and the throwing a palette in had broken and just dropped down.
While some dockies are blinking and looking after the guards and rail car heading off... One walks over and drops his hat on it. The moment the car had disappeared around a corner, he picked it up. Now, all this gold has been accounted for when it head headed off so, officially, it was still there on the count.
Apparently he kept it in the back of his shed, and every month or so, he'd saw a corner of it off, melt it down, and go sell it to a pawnbroker and then have drinking money and buy drinks for his mates for the rest of the month.
Too much hassle to try to get rid of that much raw gold at once, so he just.. simply used it for drinking cash over the next batch of years.
