A bill-handling device provides relative movement between a sensor and a U.S. bill or other object to permit that sensor to sense longitudinally-spaced areas on that U.S. bill or other object which correspond to areas, on authentic U.S. bills or counterfeits thereof, where significant data is found. Data which is obtained during the sensing of those areas is stored, and subsequently is analyzed to determine the authenticity and denomination of the U.S. bill-if it is one of a plurality of bills of specifically-different denominations.
