David Akers (1975/88): The 1880 is very similar in overall rarity to the 1879 but it is even more difficult to obtain in choice uncirculated condition. As a date, the 1880 is also on a par rarity-wise with the 1855, 1856, 1857, 1858, 1863, 1864, 1869 and 1870. It is more rare in unc. than the first four listed but not quite as rare in mint state as the last four. The majority of 1880 twenties grade VF or EF. In AU condition, the 1880 is very scarce and in average Unc. it is rare. A few choice and gem uncs exist but they are very rare.
