Sorry, I have no old boards for sale. I am often asked the worth of old WA HOO boards. The boards shown on this page were made anywhere from the 1960s through the 1980s. Most are not that rare and I guess they are worth what you are willing to pay for them. I have purchased them at flea markets for $10-$20, but sometimes see them sold on eBay for as much as $50.
If the board you have has sentimental value, it would be worth more to keep it and hang it on your wall as I have done with my old boards. They are all hanging in our game room.
Regards,
Chuck
