Cloud City 10123 is 698 pieces. That would've retailed for around $70-$90 new.

It is worth roughly $10,000 sealed in box.

I have some of the original Lego Star Wars sets. All opened and built and etc.

Including this one which I purchased for like $5 or $10

I also have the only Deadpool figure Lego ever put in a set that goes for $75 or $100 by itself. It was in a $20 set.

So the amount they spent could be somewhere in the thousands, but probably below $100,000.

Wow. I do not want to knock collectors but I will never understand them. That particular set worth 10k looks kind of crappy to me. I understand the star wars crossover appeal but still. And I have three kids and have bought countless sets. Every bday and xmas times 3.

This set is expensive mostly due to rarity.

The screenshot of the Facebook post says they purchased the sets for approximately $20,000.

But it is then a greater fool "investment" unlike stocks.
