If you’ve lost change as you’ve gone through the security machines at the airport, don’t worry. It’s in the hands of the Transportation Security Authority.

According to CNN, the TSA took in almost $675,000 in 2014, which is slightly more than the $638,000 they took in during 2013, but 76 percent more than the amount collected in 2008.

New York City's John F. Kennedy International Airport claims the top spot for most loose change. Passengers left behind $42,550 in spare change at the security checkpoint, according to the Huffington Post.

A spokesman told CNN that the TSA tries to give lost items back to passengers if they can, but loose change, if unclaimed, is turned in and documented at the TSA financial office.

The lost money is used to fund security operations.
