New YORK - States are making a profit off of airplane passengers' banned belongings.

Each month, about 425 pounds of personal items end up in the Transportation Security Administration's hands at the nation's biggest airports. Many of those items are a variety of knives, some of which will now be permitted due to a change in TSA policy.

The TSA boxes up surrendered items and sends them off to states that want to earn extra money.

Pennsylvania has made almost $900,000 in the past nine years by reselling items that could not get through TSA security. Some items are sold at a government surplus store, but most are sold on the website.

Passengers always have the option of mailing banned items home, checking them in their luggage or voluntarily surrendering them to the TSA.
