Keep an eye on the paper bills you accept at the register when exchanging your hard earned money. Counterfeit bills are circulating around the country and here in Arizona.

Police in Kingman have confirmed the bills look legitimate from the paper to the printing, but they each have strange Chinese stamps in red and black ink on them.

When translated, the stamps read, "Skills Practice Coupon," "Specimen" and "Circulation Prohibited."

The latest batch of fake bills showed up at a truck stop in Kingman this week, but Mohave County Sheriff's deputies intercepted a batch in the Lake Havasu region back in March.

The money is supposedly from China, used to train bank tellers how to handle foreign currency exchanges.

The cash is useless in the United States. and anyone who finds the mutilated money should call local police.
