Police are looking for a group of thieves they say stole two million dimes from a tractor-trailer in Philadelphia early Thursday morning, KOAT reported.

“Overnight, a carrier parked his tractor-trailer [with $750,000 worth of dimes inside],” Philadelphia Police Department Captain John Ryan told reporters.

“Common practice with drivers to pick up loads. He was going to Florida … They park the truck overnight to get on the road in the morning.”

In this case, the tractor trailer was stuffed with dimes from the U.S. Mint in Philadelphia. It was parked in the Walmart parking lot of Philadelphia Mills, a shopping center in the northeastern part of the city.
