This issue is by far the most common of the series in Mint State. This is a "hoard" issue with several small to medium sized hoards of Uncirculated coins dispersed in the 1970's and 1980's. Locating a specimen in MS-63 or lower grade is no problem at all but in MS-64 and especially MS-65, this issue is much more difficult to find than most people realize. True gems are genuinely rare and superb (better than MS-65) quality examples are essentially unobtainable.
The 1909-D is usually well struck (as are most Denver Mint gold coins) and they are seen both satiny (uncommon) and with a "soft" frosty finish. The lustre for this issue is good to very good, much better than for the 1908-D. Color is wide ranging from coppery gold to greenish gold to bright yellow.
