@Grogg awesome!
whadaya have? I’m just being 👃🏼 !
eBay tends to be a good place to sell, but for expensive sets i’d only get involved when they have the lower selling fee offers. I’ve seen some very limited edition (employee-only) sets going for serious money, so plenty of collector-type buyers.
Bricklink is my go-to for guide prices.
Selling wise, I would think it’d be pretty good too, but not sure how much their fees are.
