The Kingman Police Department has issued an alert about counterfeit money.
The fake bills were discovered at downtown businesses and have been found throughout the United States, police said.
Photos released by Kingman police of the counterfeit bills show three lines of simplified red Chinese characters on both sides.
The counterfeit bills can be found online, and some are being sold.
eCRATER, an online marketplace and free online store builder, describes the counterfeit bills as bank notes that are usually used by Chinese bank tellers being trained in handling foreign currencies.
Kingman authorities are encouraging individuals and businesses to be alert for any attempts to pass the counterfeit money.
Anyone with information is urged to contact any law enforcement agency or Mohave Silent Witness by calling 928-753-1234 or sending tips online to kingmanpolice.com and clicking on “Give A Tip.”
