I have a pair of unmounted and never used K2 FOUR skis I got back in 1972 or so. They are in new, perfect condition.
Do you have any idea what they might be worth?
Not much to be honest. I would say IF you can find the right buyer...mayyyybe $50-100?
Ya, put them in storage next to that BetaMax and SVHS gear. The resale and collector appeal is similar for those items as it is for old straight skis. There are some luddites that like to collect and play with them but not willing to pay a lot for the pleasure.
It was...but they were using nostalgia for the old straight K2 Four to sell shaped K2 Fours.
