Series 26470 Price variances

[narkotic]

Curious on why such price discrepancies exist in this particular series of AP. I like this series as it's a better used price market.

The "elephant" / "vampire" appear to be the lowest cost. But then the ghost is near 10k more just for the ceramic bezel? Is there something else I'm missing?

There is also a ceramic vampire which carries the same premium.

Then there is a blue dial model that is not ceramic but priced like the ceramics.

Hoping an expert can chime in here. I like this series as they are a bit on the newer side and I appreciate an open case back for 20+K I enjoy seeing the movement myself as I appreciate the art. I also like that nothing is coated in that odd rubber material (pushers, bezel, etc). Cheers.
