Passengers left behind $409,085.56 in spare change while going through airport security checkpoints last year.

This is a crazy amount of money considering TSA isn't forcing us to leave the money.

Check out some of the highest collecting airports in the country.

According to Thehill.com the top five combined for more than $100,000.

The biggest haul by far came at JFK, where about $47,000 was collected, followed by Los Angeles International ($19,000), Atlanta's Hartfield-Jackson ($16,500), San Francisco ($16,000), and Miami International ($15,800).

The TSA gets to keep the loot, though a Florida congressman (Rep. Jeff Miller) wants to make the agency give it to United Service Organizations in the future.
