Found at the dump

So I found this old vintage Nash sidewalk surfboard at the dump. I'm not sure if it's worth anything since I found it at the local dump. I'm not the type to bring things home from the dump but seems to be in great shape . I guess I'm hoping someone can tell me if it was a good find or not. I had a couple Nash boards when I was kid in the 80s but this is much older style then what I had. So if anyone can help I would really appreciate it. Hopefully it was a good find so my girl will stop yelling at me over me bringing it home. lucky 1336 at gee mail .
