Of the two main varieties of 1873, the Closed 3 variety is by far the rarest. In fact, it is one of the rarest P-Mint Double Eagles, roughly on a par with the 1862, 1868 and 1871 and just a little less rare than the 1859. Most known specimens are in the VF to AU grades and true mint state specimens are undeniably rare. I have never personally seen a choice or gem mint state specimen and no more than a couple of average Unc-60 quality.
The Saddle Ridge Hoard of gold coins, discovered in northern California in 2013, contained only one 1873-$20 Closed 3. After earning a grade of PCGS MS62, it became a Top Pop, tied with two others as the finest example of this date.
