Not everyone is rich enough to throw away such a perfectly useful sword. You won't be able to sell this very easily (at all), but I also wouldn't be in a rush to merch it. Toss it on a hero and see if you ever use it. If you do (even for one quest), it's worth more to you than the 248g the merchant will give you for it.
1. salvage the +30, those go for ~8k nowadays
2. afterwards if the sword hasn't broken yet, you could try to salvage the zealous and get maybe 1-2k for it
3. i would merch the sword
