Why is the sword worth $150k? Did it appear in something famous? Or is it just because other Weta Workshop items have appeared in famous films?

Because the market for such items include people who are willing to believe it is worth that much.

It's probably because it has something to do with Stephenson's notorious failed Kickstarter sword fighting game "Clang."

Because of the "twinned NFT," of course.
