  24. Counterfeiting In 1996 the government starting adding new security features to our paper money due to the advanced copying technologies that have raised the incidences of counterfeiting. The $20 bill entered circulation on October of 2003, followed by the $50 in September of 2004, and then the $10 in September of 2005. Subtle background colors have been added along with other features to discourage counterfeiting. Kendall/Hunt Publishing Company

  25. Woman Brings Fake $10,000 bill to the BankBy Associated Press Oct. 20 2010 Lowell, Mass. (AP)- A $10,000 bill? The staff at a Massachusetts bank just wasn’t buying it. The suspicious staffers quickly determined that the bill a woman brought into the Lowell bank was a fake. Michael Gallagher, risk management director at Enterprise Bank, tells The Sun of Lowell that it is believed there are only about 300 $10,000 bills left, and most are in the hands of collectors. The bank called the police, who in turn notified the Secret Service, the agency that investigates counterfeiting. Gallagher would not say what kind of transaction the woman attempted with the note on Tuesday. The woman’s name was not released because she has not been charged, but a police spokesman says she may have mental issues. Kendall/Hunt Publishing Company
