David Hall:
The 1924-S is rare in circulated grades, one of the rarest of all Buffalo nickels. It is also rare in mint state, and it is very rare in Gem condition. There are only three dozen or so Gem quality examples known. Strike can be an issue with the 1924-S, but usually not as much of a problem as with dates such as the 1918-S, 1920-S, 1923-S, and 1925-S. Luster is usually a little sudued and somewhat satiny looking. In any grade, the 1924-S is one of the key dates in the Buffalo nickel series.
