What are the dimensions? If they are cap construction I'd say they are silencers/missconduct except those models only had 1 rivet in the tips/tails. They look like they're in mint condition. They might be worth like $2-300 with the bindings.
they are k2 extremes with diff base/ topsheet I doubt anyone would collect them for that reason so they would be worth the same as a regular 10 year old park ski in similar condition.
