Brian Bell, a spokesman for U.S. Customs and Border Protection, said officers at the Cincinnati/Northern Kentucky International Airport drilled into one of the presses' rollers Saturday when the X-ray scans appeared unusual and found a cache of $100 bills, the Cincinnati Enquirer reported Tuesday.

Bell said the officers opened up the rest of the 16 press machines and discovered nearly $640,000 in cash.

The spokesman said officers are trying to track down the sender in Mexico and the intended U.S. recipient.
