1906-O 50C G6 Certification #41385290, PCGS #6506
The 1906-O Half Dollar is definitely scarcer in Mint State than the 1905-O. In fact, the 1906-O is one of the toughest dates among all the O-Mint Barber Half Dollars -- only a few have smaller populations of certified Mint State examples. The 1906-O Half Dollar really shines on the high end, where a number of superb examples top off the condition census. All of the best 1906-O Half Dollars got there because of their amazing, colorful toning. Two standouts include a pair of PCGS MS67+'s from the Hugon-Shireman and Price-Duckor collections (if those names seem familiar it is because they all assembled world-class groupings of Barber Half Dollars).
Unlike most of the other O-Mint Barber Half Dollars, the 1906-O is usually well-struck and fully detailed.
David AkersIn my opinion, this is a very underrated issue, one that is more rare, especially in Gem condition, than the 1905-O which had a mintage of only a little more than one fifth as great. It is also very nearly in the same rarity category with respect to Gem condition as most of the more publicized, and generally more highly regarded, O Mint issues from 1892-1904.
