David Hall: The 1911, 1912, and 1913 Philadelphia Lincoln cents are of very similar rarity in virtually all grades including Gem Full Red. They are tougher to locate than the 1909 and 1910, but not quite as scarce as the 1914 and 1915. Full Red Gems are definitely scarce and Superb Gems are rare. The typical 1913 is very sharply struck and some specimens have nearly proof detail. Luster is often excellent and Full Red examples usually have a deep red color.
