Other major DDOs are the 1866 S1 and 1887 S1. They're less dramatic than the 73 S1 but are even tougher to locate -- the 1866 is 3X and 1887 2X as rare. The 1866 S1 is a rare multiple variety coin with misplaced date digits in the pearls and denticles (see images on MPD page). The 1887 S1 is particularly elusive in higher grades.
