Trying to find out what this board is worth..

I have this Dewey Weber 8ft. 6 Longboard I got from a friend. People say it is from the 1970's but I dont know much about it. The name Bendiksen is visibly handwritten under the fiberglass on top of the board. It does have a hole in the bottom of it and a couple of dings and patches around the board. I have done some research on Dan Bendiksen and know he was a shaper. If you guys could help me out with some info on this board that'd be totally awesome. Here are some pics of it..
