THIEVES STEAL NEWLY DESIGNED $100 BILLS THAT ARE UNRELEASED AND CAN'T SPEND

Unintentionally released: A batch of newly designed and unofficially released $100 bills, one pictured, were stolen from a Philadelphia airport on Thursday

A 'large amount' of newly designed and unreleased $100 bills may be out on the streets sooner than expected.

A courier reported a large theft of the colorful C-notes originally set for release in 2013 while bound for New Jersey's Federal Reserve Building in East Rutherford on Thursday.

The heist of the unique bills is said by the FBI to have taken place sometime around 10:25am after landing at Philadelphia International Airport from Dallas, Texas.

It was only until the shipment arrived around 2pm at the Federal Reserve Building that the courier service noticed and reported it missing to the FBI.

Agent Frank Burton Jr. said the cash was stolen from the plane.

With a new design and sophisticated elements to thwart counterfeiters, investigators said these Benjamins are easy to spot. 

Along with a large gold '100' graphic on its backside, they also feature a new orange inkwell and a bright blue security ribbon.

Arrival: The bills arrived at the pictured Philadelphia International Airport from Dallas, Texas on Thursday morning where the FBI believes they were stolen

Gone: Several hours after their landing and arrival at the Federal Reserve Building in New Jersey the bills were noticed missing and reported to the FRI

There's also a disappearing Liberty Bell.

Describing the amount taken only as a 'large amount' of bills, agents aren't giving specifics.
