I gave the OP the correct answer instead of a crystal ball guess
So basically you gave him no answer (just list it for sale), spammed his price check thread, and belittled the price check opinions of those who actually did give him an answer. Got it.
It seems this "debate" over how awkwardly items are valued from time to time would be better off in a discussion thread. None of these concepts are new.
To the OP: The only reason I keep replying to this is to give you confidence that this shield is in fact worth more than some may say regardless of "better" or "more rare" shields being listed or bid on for less. You found a gem.
