Assuming it's in nice but routed condition, probably around $1000. Fun game. Apparently the sounds get annoying, but someone has made a modified ROM the changes that.

For the display, you can get a used replacement around $100, new plasma display around $200, or an Xpin LED display around $275. Personally, I'd go with that for longevity; it's not a time bomb, unlike a plasma display.

Is the playfield worn through to the wood? Or is it just insert wear (chipping of the plastic bits that're inlaid in the playfield?)

If you have pictures, it would be easier to gauge price. One man's "nice" is another man's "blown-out playfield worn to bare wood."

I picked up a game today in what was supposed to be "fair" condition from 1986, with no mylar or clearcoat; the playfield has no wear, insert lifting or cupping, and the backglass is perfect; it's got minor planking and minor sideart issues, but I would've said it's quite a bit better than "fair."

That is actual playfield wear; it's down to bare wood.

It's rare to see a clearcoated game worn through like that; that's probably one of the rougher working LW3 pins out there. At this point, you have to think about how bad you want the game, and how long you're going to want to keep it. A pin made after about 1990 with that much wear is generally a tough sell, so if you think you may not want it semi-long-term, that's something to keep in mind. I'd say anywhere between $500 and $1000 COULD be reasonable, depending on the pin market where you are. I'd say $700-800 is probably fair. I don't think I would've spent more than $800 even when I was actively looking for a LW3.
