Police in Ocean City said Wednesday that they've received 10 complaints of counterfeit money used at local stores since June 18.
The denominations range from $20 to $100.
Police say the counterfeiters are washing out the printing on smaller bills and changing the numbers to larger denominations.
The bogus bills are being discovered when merchants bring them to banks for deposit.
