I'm catching flack in my inbox about my above comments.
Let me clarify, if you are going to play a NIB 80s game, you HAVE to clear (or otherwise protect) the playfield.
If you just start playing on it, you will instantly see insert wear; because the wood fibers were not compressed when the paint was fresh and flexible.
You will also have tons of airballs from the cupped inserts.
You see those problems all the time when somebody finds a NOS playfield, installs it, and then sees it wearing at an alarming rate.
My collector value comments were more aimed at those "0 mile" collector cars that are rolled on and off trailers and never driven.
