The 1915 Philadelphia Lincoln cents are common in circulated grades though it is a tougher date in the uncirculated grades and a true rarity in the Red uncirculated grades, particularly above MS65. Only a relative handful of specimens are known in MS66 and but a few in MS67 or higher. In all respects, the 1915 penny is one of the toughest Philly-mint Lincoln cents around, behind perhaps only the 1914 Philadelphia Lincoln cent.
