Leatherfoot Raider Cap
 

Human, Karana Ranger that has Kindly faction with Marshal Anrey, I turned in the Polar Bear Skin, Alligator Skin, Grizzly Skin and Shark Skin all at once and received nothing back.

How thick was the grizzly skin?

it was pretty thin. I destroy all thick grizzly skins on principle.

The shark skin can also be the wrong one. Two items same name, one is stackable non-lore (correct one) and the other non-stackable lore

You can also turn in to the npc behind him on accident.
