The 1908-S seems to be a popular low mintage issue amongst gold pieces but this Half Eagle in particular is more common than one would think. The mintage is certainly on the lower end at 82,000 but many of those were saved unlike other higher mintage issues that are actually rarer. It is a relatively attainable coin up through gem condition with a very gradual rise in value until the absolute finest MS68 gems that sell for very solid six-figures. This coin may not be underrated but is certainly not common. In addition the surfaces can be found with an array of golden hues, levels of luster and mostly all of them have a strong strike.
