Did you know that the $1 bill has not had a face-lift since 1963? Did you know U.S. currency is one of the most difficult to counterfeit and that most notes have over a dozen anti-counterfeit features? Did you also know that the detection of counterfeit currency is under the purview of the United States Secret Service? Students and guests in Introduction to Forensic Science learned all this and more when alumnae Julia Wikoff Barker (BS'10/MS'11) visited to give a seminar on questioned document evidence. Julia brought samples of currency, both authentic and counterfeit, for students to examine, and quizzed everyone on their ability to match handwriting samples. She is a chemistry and forensic science graduate and is now a Forensic Document Examiner for the U.S. Secret Service. In her work, she examines all kinds of evidence, from falsified contracts and identification to counterfeit currency.
