POWELL, Wyo. (AP) — Powell police say at least $440 in counterfeit $20 bills have been passed to businesses during the holiday season, and counterfeit money is still turning up.

Police Chief Roy Eckerdt tells the Associated Press the bogus bills that officers have collected so far lack the security strip and exact coloring of legitimate bills.

He said the bills apparently started showing up on Dec. 21 and Dec. 22.
