Hi Matt. Firstly, as there were 400 & 2000 of each made respectively then they cannot be classed as rare. That's plenty of sets made to go around! Price will vary with the tides & the winds & depend on the phase of the moon but I paid $75 per set. The last guy to offer them up wanted (I think?) about double that. Somewhere in between may be about the right mark. The condition that you say they are in will definately add a few $$ to the value. A good place to start if you're looking to sell in on this board. You can always make a post (definately with images!) & a price & see how you go. If no takers then give ebay a blast where you'll get much more exposure. Good luck mate!

Cheers, Tim.
