Secret Service agents told FOX23 a large counterfeit money operation is moving through Green Country.
Special agents showed FOX23 the fake $100 bills they've been collecting as evidence, so far more than a dozen in Tulsa and more will likely show up.
She was just trying to sell a $3 drink.
"He asked for a change for a $100 and I said 'yeah,'" said Smoothie King employee Aubrey Bowles.
She said when she took the $100 bill she thought it was real.
"It looked normal to me," she said.
But it wasn't, after her boss tried to deposit it at the bank Bowles found out it was fake.
"I just felt really bad," she said.
She's not the only victim.
FOX23 learned the Secret Service is working what agents call a "large counterfeiting operation" with numerous people involved.
Agents said so far they know, the operation has moved through Tulsa, Oklahoma City and Missouri.
Agents talked to FOX23 off-camera because they often work undercover.
The reason so many are duped by this $100 bill is because the pen used to reveal a fake didn't work on these $100s because the counterfeiters used legitimate one dollar bills to make the fake $100s.
Agents know all these bills came from the same operation because they have the same rubber stamp and serial number.
Whoever made them made them look like the old one hundred dollar bills. Agents say those are easier to fake than the new ones that came out in 1996.
Agents tell us shopping malls have been targets, including Tulsa malls and on Tuesday the Smoothie King at 51st and Yale got hit.
"It's just not fair, not right," said Bowles.
Agents told FOX23 how to spot the fake ones.
For one they look like the old $100 bills.
The counterfeits all have the same rubber stamp mark, the same serial number and you can faintly see a number that was on the original bill.
And the printing itself, like the president's face, is a little blurry and not as crisp as it should be. They said the ink will also smear when it gets wet.
Tulsa agents have already collected more than a dozen of these so far, but say they're showing up nationwide.
