Ron Guth:
The grade distribution of the 1871 $5 looks markedly different than when David Akers wrote about this date decades ago. He knew of only two AU examples (presumably the finest known to him), but today we know of at least five Mint State examples and well over a dozen AU's. Part of the increase in the number of high-grade examples can be explained by the appearance of a new pieces in the marketplace, but it can also be attributed to the careful compilation of population data over the years for a date which normally wouldn't have meant much to Mr. Akers (unlike the rare dates and condition-rarities where he excelled). Unfortunately, there are still no beauiful 1871 Half Eagles -- the best ones known to us are somewhat baggy MS61's.
