David Akers (1975/88): The 1900-S is very scarce in any condition, on par with the 1882-S, 1883-S, 1884-S and 1897-S. In strictly uncirculated condition it is rare and choice or gem quality specimens are very rare.
David Hall: This is a very underrated issue in Gem condition. There are two true miracle coins...both graded MS67 by PCGS. Other than those two coins, I have not personally seen an example I would grade strict MS65 or better. One of the MS67 coins is the Clapp-Eliasberg coin. The other is a coin that showed up in the 1980s and traded hands a few times since that time.
The Clapp-Eliasberg coin was obtained directly from the mint in the year of issue by John H. Clapp. Louis Eliasberg obtained the coin when he bought the Clapp collection intact in 1942. In the October, 1982 Eliasberg sale, Gordon Wrubel and I bought the coin for $14,300, a big price at the time.
