From "Looking through Lincoln Cents" by Charles Daughtrey:
Quote:
"Called either type 1 or 2, large date or small date the size didn't change much...the difference in the clearance between the motto and the rim. The first design used (large date) has very little clearance between the rim and letters of IN GOD WE TRUST, has thicker and more blunt digits in the date. The small date design has more space between the motto and rim and sharper more pointed digits in the date. Both types were struck in business strikes at all mints, however all proof cents are large date."
