Counterfeit $20: Suspect 'looking like a methamphetamine user'

MYRTLE CREEK, Ore. - A man passed a counterfeit $20 bill at a gas station Saturday morning, police said.

The white male in his 40s "was described as looking like a methamphetamine user," Myrtle Creek police said.

The man used a $20 bill at the Penny Pincher gas station around 11 a.m. that was determined to be a counterfeit, police said. The serial numbers on the bill are JG34691899A.

The man was seen leaving the scene in a Red Dodge Durango.

Police in Eugene have said $20 bills are the most popular bills to counterfeit because they are easier to pass than larger denominations. Smaller bills - even counterfeit $1 bills - are not unheard of.

Last week, police in Eugene announced several hundred dollars worth of counterfeit $20 bills had been found circulating in town, police said.

"While the total amount of fraudulent money didn't exceed more than several hundred dollars, investigators believe it serves as a good reminder to brush up on your money authentication skills," police said.

Merchants who get a bum bill are out that amount of money. Counterfeit bills cannot be exchanged for real ones.

The U.S. Bureau of Engraving and Printing embeds security measures in each bill that make it possible to identify counterfeit bills.

From colors to printing to artwork, bills are made difficult to fake - and easy to ID as legit.

Last summer, police in southern Oregon seized $200 worth of counterfeit $50s.
