1911-D Indian Quarter Eagle. MS-65 (NGC).This is a remarkably well preserved and attractive example of the key date 1911-D quarter eagle. It is sharply struck throughout including a crisp D mintmark. Both sides also exhibit pleasing satin luster and warm golden-orange patina. Very smooth for both the type and issue, this impressive Gem would do justice to the finest collection of 20th century U.S. Mint gold coinage. While it is the first of only three mintmarked issues in the Indian quarter eagle series, the real desirability of the 1911-D stems from its key date status. With just 55,680 pieces produced, it has the lowest mintage among circulation strike Indian quarter eagles. It is the rarest issue in its series in terms of total number of Mint State coins known, and the second rarest in Gem Uncirculated condition after the 1914-D. The present offering represents a significant bidding opportunity for advanced gold enthusiasts.
