Here is a list of all the Rapiers found in Ancient Anguish. You should use the most difficult rapier you can without missing the monsters you try to hit very often. If you stick with a very-easy or extremely easy rapier for a long time, you won't get your skills up very high (you need a challenge to increase your skills). I only have sell/buy values for rapiers I have sold and bought. Remember that the Sell/Buy Value changes depending on the shop and your Trade ability.

I've been asked about thunt rapiers. With the exception of Magic Rapier and Rapier of the Defender, I don't much like them. If you want to use thunt rapiers, they're usable in the 30-40 skill range.
