Greg Noll has a lot of sentimental value if nothing else. A true legend.

You can sell it on Craigslist or any public bulletin board around town. Ebay will be complicated because you have to ship it. The value will generally depend on the brand, shaper, year, and most importantly the overall condition.

Start with the year and condition and search for other used boards.

Before you price your board, go to an antique board auction and compare what you have to the ones displayed or sold. Auctions are held in many places in California, often with big surf contests, Surf EXPO, or other similar events. You might want to contact the Coalition of Surf Clubs and ask if they know of any in your area. On the East Coast, you could contact the East Coast Hall of Fame Museum and nationally you can also contact SurfTrader.
