He was using some of it at the Arkansas State Fair.
Twenty-nine year-old Marcus Bledsoe is now charged with 53 counts of forgery.
Police say when they arrested Bledsoe Tuesday night, he had about $1,400 worth of fake cash, mostly in 20's.
They are pressing charges for every bill they got from him.
Over the weekend, two vendors were questioned but they weren't arrested.
Police and Secret Service agents are now interviewing Bledsoe to see if he was behind it all, or if others were involved.
They are matching similarities in his cash to other fake bills.
But while in the past, other counterfeit crooks try to exchange their fakes for real change, police say Bledsoe was doing something different.
Officers say he was caught simply making large purchases with imitation bills.
"For the vendor, he knew his money, knew it was counterfeit, with the number of people out during that time of day, they were lucky to get Mr. Bledsoe and identify him," said Cassandra Davis with the Little Rock Police Department.
We're told Bledsoe had purchased big stuffed animal prizes: three of them at about $100 a piece.
He pleaded not guilty in court Wednesday but his legal process has only begun. He could also get slapped with more charges from the feds.
