David Akers (1975/88): Despite its substantially higher mintage, the 1878 is essentially identical with respect to both overall rarity and condition rarity to the 1877. It is also very similar in overall rarity to the 1854 and 1860 although it is not quite as rare as either, especially the 1854, in full mint state. The 1878 is not deserving of "common date" status. Choice and gem uncirculated examples do exist but they are surprisingly rare.
