Merchants: Rusty Two Handed Sword

[Etast]

Name: Etast
Race: Ogre
Class: Shadowknight

Issue: Quest reward turn in for giving 4 Lizard Meat to Soonog (Ogre SK GM) in Oggok results in a Rust Two Handed Sword as a reward. Sale of said Rusty Two Handed Sword(s) to all merchants (I've tried) results in 0g0s0c even though the merchant tells me he'll buy it for 2g7s9c.

After transaction, it says I received 2g7s9c but I receive no monetary compensation.
