York State Bank officials have been working with local law enforcement on the recent discovery of counterfeit money.
Published reports reveal that a counterfeit $10 bill turned up at the bank this week.
The bank discovered several weeks ago that counterfeit $100 bills had been passed to local merchants.
York Police Chief Don Klug says comparing the water mark to the image in the middle of the bill is a good way to detect a fake. The images should match.
Also, he says, when a bill is turned in bright light, the numerals in the corner should change colors. The colors won't shift on a counterfeit.
