If it's not inscription: Salvage the 20/20 and sell for 15-18k.
If it is inscription, then it could go for quite a bit regardless of it's colour. Not sure if it'll hit 100k, but definitely around 50, imo.
If it's inherent and you salvage the 20/20 successfully, then you'll still get 5-10k for it. Fellblades are a very sought after skin, especially cheap and functional ones.
