They have value as to decor. We used to sell that stuff for close to what new old stock skis go for, $300-400 bucks. There are suppliers that specialize in that stuff. If I can remember the name of the outfit that we used to get them from, I'll let you know. Something like Ski Country Antiques... Yes! http://skicountryantiques.com
See if they'll buy them. Probably won't give you that much, though. Maybe $50-100? They look like they've got that center ridge people like, but not very glossy.
You don't say where you are, but if they won't take them, they might be salable in ski area towns on Craigslist or a flea market or local antique shop. Less so in a metro area.
