1879-S $20 MS60 认证号37685191, PCGS号8991

David Akers (1975/88)

The 1879-S is more rare than the 1877-S or 1878-S and it is also rarer than the 1874-S, 1875-S and 1876-S. Although it is generally regarded as a common date, the auction data correctly show that the 1879-S is really not common at all, particularly in high grade. In low circulated grades, i.e. VF or EF, the 1879-S is only moderately scarce and it can usually be located without much difficulty. However, in AU the 1879-S is scarce and in average uncirculated condition it is very scarce. Choice and gem mint state examples are known but are rare, especially gems which are virtually impossible to obtain.
