Nassau police recently arrested a man for allegedly spending counterfeit money at the Roosevelt Field Mall in Garden City, and they warned residents Monday about a rise in fake $50 bills.

Police say a man tried to use 57 fake $50 notes before an alert cashier noticed and informed a security officer. According to the Secret Service, the well-made counterfeit bills do have flaws. The Secret Service points out an inconsistency between the right and left corners, where one side lists "C-3" and the other "C-1." There is also a printing defect on the zero.

Experts say it is very difficult for the general public to notice a counterfeit. They say paper quality and feel is key to spotting fakes. Those who believe they have received counterfeit money can return the bills to a bank, but should not expect a refund.
