Market depth

What it's actually worth

The three-tier spread, verified comparable sales, and where this title sits inside its cohort. Live snapshot lives above in Pulse; this is the time-and-context layer.

Three-tier spread · log scale

The same game at three prices — Loose, CIB, and Sealed on one ruler. The scale is logarithmic: each gridline step is 10×, so the distance between bars shows the size of the jump between tiers.
