Its outside my area of knowledge, but I do know that an actual Ritchey built MTB is worth a small pile of money. Given that he is most revered in MTB circles, the road bike might (and that is a big "might"; perhaps it worth even more because of it) be worth a bit less.
But still, far more than $100.
