The 2004 Bowers reference on the series notes: "The 1909 double eagle, 'perfect date' (not overdate) is readily available but hardly common in lower Mint State levels through MS-62. Higher grades are seldom seen, and even a nice MS-63 would be a show stopper!" More recent population data reveals that the 1909 $20.00 is fairly widely available up through MS-64, but above that it is unquestionably a condition rarity.

The example to the left was sold by Stack's Bowers Galleries in the August 2011 Chicago ANA Auction, where it realized $132,250.
