I own one, so take this with a grain of salt those of you that want to price police, but...
JP is all about the hole wear. If your C hole and A hole are blown out, you'll get much less money for the game then if they are nice looking. I've seen C and A holes that are so blown out the ball coming out of the pops will change trajectory and sometimes just slip into one or the other. Because of that, people that have holes with little wear can get a lot of money for them.
And yes, I realize you can read that with a dirty mind and giggle, and if you just did that, you're welcome. But I'm also serious.
I have a NICE Jurassic Park. It has almost no hole wear. The last time I had it out and about, I had people offer me $3k for it because of how nice it was, and I turned them down. And, this was back when you could pick up a Jurassic Park easily for $1,000.
With the hole wear that you have, I would start at a higher price point. That's not typical wear, it's minor wear. If you don't need to sell it, I'd start closer to $2500 or even a bit higher than that, and work your way backwards. It might take you a while to sell, but you'll get more for it in the end. If you need to sell it now, a price of $2kish and it will walk out the door within a week I would guess.
That's a very nice example of a game that picked up a ton of wear in the field. Good luck with it. I wouldn't (and didn't!) sell mine for $3k! New code is going to be great too, and should give it another little push.
