Nowadays, almost everyone relies solely on their debit and credit cards for standard transactions, leaving the value of the dollar and simple change in the dust.

The newest report from TSA is proof of this enough.

According to USA Today, over $765,000 dollars in loose change was left in the plastic buckets and bins at airport security checks in just 2015 alone.

Once this unclaimed cash is collected and counted by the Transport Security Association (TSA), it’s theirs.

That’s three-quarters of a million dollars that accidentally went from travelers’ wallets, bags, and pockets to the TSA in just one year.

“TSA makes every effort to reunite passengers with items left at the checkpoint, however there are instances where loose change or other items are left behind and unclaimed,” TSA said in a statement. “Receipts of unclaimed money are deposited into a Special Fund account so that the resources can be tracked easily and subsequently expended.”

In the past 5 years, these dollar amounts have only continued to grow. Here are the amounts collected by the TSA since 2010:

2014: $674,841.06
2013: $638,142.64
2012: $531,395.22
2011: $487,869.50
2010: $409,085.56

So, to all my travelers out there, remember that change adds up! What falls out of your pocket will inevitably fall into someone else’s.
