Last year, the TSA collected over $865,000 in loose change from the bowls and dish tubs that move through the security check. That amount is a full $100,000 more than 2015 and seems to be steadily increasing every year.
They believe it has something to do with more travelers, who may easily leave behind a few dollars while they're trying to move through the lines. According to a 2005 law, the TSA can keep the money for civil aviation security efforts.
In the past two years, they've used it to expand the TSA Precheck program but still haven't decided how to spend 2016's cash.
Travel experts recommend that travelers stash valuables like change, your wallet, phone, belt buckles and anything metal inside your bags before walking through the x-ray machine. Obviously, it's also wise to check the bin to see if anything has slipped out unless you're not too worried about making more "donations" to the TSA.
