Filled Letter

Filled Letter.  A striking error in which a tiny die projection in the center of a letter breaks off, all pieces struck subsequent to this will exhibit the malformed letter due to a greater die cavity. The centers of O and D, the loops of A, P and R, in addition to certain figures, 6, 8, and 9 for example, are most susceptible. The part of the die which creates the center is a tiny projection that is highly susceptible to great metal stress and the possibility of breaking off. When it does separate this creates a cavity, which on the struck piece forms a filled-in letter or figure. An attempt to eliminate this problem is to grind off a portion of this tiny tall projection in the die or negative pattern.  See champs levée.  In describing a filled letter it is sometimes called "solid;" it is better to say filled, as 1930-D Lincoln cent filled D.
