The Secret Service and police have confiscated bundles of counterfeit dollars, but much of it is not American made.
The bus was the result of an ongoing investigation in Murfreesboro, and detectives said this fake U.S. currency has been flooding the market from places like Germany and China.
"We're seeing these bills with this Chinese-type writing on there," said Murfreesboro Police Detective Tyler Smith.
There's also bills imported from Germany.
"It's actually got souvenir of America," said Smith.
Imported counterfeit U.S. dollars have become a growing problem. Smith is working with the Secret Service after several large busts.
The imported bogus cash is a first for Smith, but he's also seen a jump in domestic-made funny money.
"We've never seen them in such a huge amount," said Smith.
The Murfreesboro Police Department just arrested 27-year-old Quinton Miles catching him with a large supply of fake $50 bills made for use in the movie industry as props.
"He was able to buy $3,000 on Amazon for $20 and in addition to ripping off unsuspecting customers on online sales he also sold it to other people in the community for 20 to 30 dollars for every hundred," said Smith.
He said that's how so many of these bills hit the marketplace so suddenly. It's happening now and it's a federal crime.
If you look closely you can tell most are fake, but in a rush, mixed with real money, honest people can easily be fooled even with bills made overseas.
If it's passed to you and then you are caught accidentally spending it, police will confiscate the bills and you'll be out the cash.
These days, many of the fake bills look real at first glance, but if you look closely you can notice obvious discrepancies including the texture of the paper, which will usually feel different.
