Quoted from jfh:Agree on the Addams topper.
Too high on Whitewater decal. $350+, but not $600.
I think the hologram is high unless you find a buyer for a high-end restoration but that’s going to be the most in demand. I’d suggest auctioning it off. I’m not a big eBay fan but that might be the best way to maximize value.
If it is a nos etched wh2o decal....600 plus easy. These never pop up. Last one i recall seeing went for 800.
