Would love some advice from the pros. I've got four of the original box sets from 1999. Bought at Mall of America in 1999. Unfortunately, I opened all four with plans to learn how to play... but never did. Really don't need them laying around anymore so I plan to put them up on eBay or Craigslist. I've found vast differences in what they go for so I'm hoping one of you could help me figure out how to best manage the sale.
