David Akers: The 1907-S has sometimes been referred to as a "sleeper" issue or an underrated one in Gem condition. For years, of course, that was true, but in recent times the 1907-S has come to be appreciated for its rarity more than some other issues (for example, the 1908-S...) which are almost as rare as the 1907-S in Gem condition, and yet, according to every standard pricing guide, are worth substantially less. So it may not be really appropriate to continue to describe the 1907-S as underrated, but it is certainly accurate to describe a Gem of this issue as being very rare.
