(FORTUNE Magazine) – Each year just $14 million in counterfeit U.S. bills gets into circulation -- a tiny fraction of the $268 billion circulating worldwide. But digital photocopiers could make funny money a lot easier to manufacture. Enter U.S. Treasurer Catalina Vasquez Villalpando, 51, formerly a Hispanic- affairs specialist on the Reagan White House staff. The Treasurer's main job is to oversee the U.S. Mint. She also heads the Treasury's Advanced Counterfeit Deterrence Steering Committee, which developed ''security enhanced'' $50 and $100 bills that will be slipped into circulation starting this month. The new lucre features a printed polyester strip embedded in the paper and the words ''The United States of America'' printed just six- thousandths of an inch high next to the portraits of Ulysses S. Grant and Ben Franklin. Not even the most advanced copiers can reproduce the changes, the first in U.S. currency since ''In God We Trust'' was added in 1957.
