For as long as people have been gathering and exchanging money for goods, people have also been dropping that money and losing their valuables.
Imagine your town’s annual Fourth of July celebration. There’s usually a field full of rides, vendors, and food trucks. People are congregating, pulling money out of their pockets to buy stuff, and then putting change back into their pockets. As evening comes, everyone sets up blankets and lawn chairs to watch a thunderous fireworks show.
Now imagine how much of that pocket change fell out onto the ground while people where leaning back and looking up at the sky. You’d be shocked at how much stuff people lose every single day. The more people there are in one space for any amount of time, the more stuff is lost — and the more stuff you can find!
