Just found out an older lego set that I still have (though not in it's box), is worth over $700 (more if there was a box, which I'm gonna hunt for lol)
What would be the best way to sell? Try FB Marketplace and see if there's a local collector? Figured eBay is still messy, what with the fees and chances of getting screwed around
(No, this isn't a Classifieds ad masking as a Forum Post. I could post in there if I wanted to!)
try also Bricklink or Brickowl
