It doesn't really affect the value of the other coins in the proof set. The set with the clear S will be worth more than the standard set by the difference between the clear S and the standard S. Just so you know, the centers of the "holes" in the S do not have to be shiny for the coin to be a clear S coin. It is more about the shape of the S than the appearance of the field mirror. the clear S has round curves, while the standard S has more oval curves. Also, as in your coin, the center of the S is essentially flat, whereas in the standard S the center portion is slanted. Coins like yours, where the filed mirror does show through the S are somewhat more desirable than those where it does not but that factor is probably only important when two coins are otherwise of very much equal quality.
