One variety features smaller letters on the reverse of the coin while the other has larger letters. The Medium Letters variety features more spacing between the words "STATES" and "OF" - more spacing than any of the large letter varieties. In addition: The medium letters variety features much smaller letter A's in the words "UNITED STATES OF AMERICA" with more spacing between the letters surrounding them.
