The Survival Estimate represents an average of one or more experts' opinions as to how many examples survive of a particular coin in three categories: 1) all grades, 2) 60 or better, and 3) 65 or better. These estimates are based on a variety of sources, including population reports, auction appearances, and personal knowledge. Survival estimates include coins that are raw, certified by PCGS, and certified by other grading services.
Numismatic Rarity converts the Survival Estimate for a particular coin into a number from 1 to 10 (with decimal increments) based on the PCGS Rarity Scale. The higher the number, the more rare the coin.
Relative Rarity By Type
Relative Rarity By Type ranks the rarity of this coin with all other coins of this Type. Lower numbers indicate rarer coins.
Relative Rarity By Series
Relative Rarity By Series ranks the rarity of this coin with all other coins of this Series. Lower numbers indicate rarer coins.
David Akers (1975/88):
Next to the 1875, the 1877 has the lowest mintage of any Liberty Head Half Eagle from the Philadelphia Mint. Several strictly uncirculated examples are known (I have seen one beautiful proof-like gem) and most of the others are in the EF to AU range with only a few falling shortt of that level. As a date, the 1877 is similar in overall rarity to the 1869, 1870, 1871, 1874 and 1876 and more rare than the 1866-1868 dates and the 1872.
