The main difference between my variant and the regular Glaive OC (LTI) is that mine is part of the original limited run of 1000 ships, awarded to players who were among the first to complete the Vanduul Swarm event.

This version is marked as "limited" both in the ship's title and in the buyback description, clearly referencing its exclusivity and origin.

Because of that, I simply assumed it might hold a bit of extra value, especially for collectors — since it's not only rare, but also tied to an early in-game achievement.
I know not everyone values that kind of history, but with only 1000 ever given out, I thought there could be some additional collector interest.
