1911-D Indian Quarter Eagle. Strong D. MS-63 (NGC). This is a lovely example of a classic key date issue in the Indian quarter eagle series of 1908 to 1929. Handsome orange-gold patina blankets both sides, and there are glints of pale olive also evident under a light. Sharply struck with virtually full detail throughout the design, the soft satin luster enhances the appeal of this inviting Choice Uncirculated coin.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. 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 collectors of 20th century U.S. Mint gold coinage.
