Alan, it is not just the number of coins minted, it is the population available, both for total circulation and by grade. I don't have a book with me so just checked PCGS pricing as an example. If you look at the 1931, in G-4 it is $2 and MS-60 $20 or 1000% increase. The 1931-S you are looking at is $115 in 4 condition and $195 in 60 or about an 80% variance. Obviously, to me, the price on the lower grade 1931-S is based on the total mintage, more or less, and the MS-60 is then adjusted based on population in the grade. In other words, there are a lot of high grade 1931-S coins relative to the overall circulation. anyway, that is what makes sense to me.
