And the short answer is 8-10pp per stack of bone chips and 3-4pp per LQ/MQ pelt. Also spider/ling silks go for 10-20pp per stack. These can take time to sell. If there is no buyer within about 5 minutes, I go back to hunting. HQ bear pelts go for 30pp and tend to sell faster.
Edit: Personally, I don't find Grimjaw's link very useful. Try the project 1999 Wiki instead:
