Coins are de_signed to facilitate small, everyday purchases - a newspaper, a cup of coffee, a loaf of bread - while bills should be reserved for more expensive purchases. The small size and portability of coins makes them easy to carry around and pull out of one''s pocket a moment''s notice, in stark contrast to paper money wedged into a billfold
