1906-O Barber Quarter. MS-67 (PCGS). The 1906-O Barber quarter is represented by a small number of beautifully toned Superb Gems in todays hobby. The Pogue specimen is one of these coins, a solid Condition Census example that features reddish-gold, powder blue and silver-rose iridescence on both sides. The luster is full and frosty, and the striking detail is razor sharp from the rims to the centers. The commencement of coinage operations at the Denver Mint that year may have resulted in a slight decrease in commercial need for the 1906-O coins. For whatever reason, a greater number of Mint State coins survived. Mint State survivors of the 1906-O are still scarce however, as the vast majority of coins saw extensive commercial use. Among the finest certified, this premium quality Superb Gem is rare from a condition standpoint and would serve as a highlight in the finest collection.
