Selling jackson all star, Kendo Eskimo, Mad River Revelation

We are downsizing our boat collection. We have a three boats that are older but used very little. I was wondering if I could get some suggestions on how much they are worth. There is a beautiful lime green Jackson Allstar with happy feet, Kendo Eskimo playboat kayak, and a gorgeous Royalex Mad River Revelation. I really appreciate an idea of what they are worth. I have not kept up on cost of boats.
Thanks,
Linda
