I have this shield, and I'm wondering if its perhaps worth anything or should it be sold to a merchant?

Edit: Added Description
Militia Shield of Endurance
Armor 16 (Req. 9 Tactics)
Health + 45 (while in a Stance)
Inscription: "Sheltered by Faith"
Received Physical Damage -2 (while enchanted)
Thank you if you decide to help me.
