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.

Why this title

Why collectors care

The cultural context, the production lineage, the place this artifact holds in its console's history.

he Black Onyx is a role-playing game developed by Bullet Proof Software. It was released, among other consoles and computers, for the SG-1000 in 1987. It was the last SG-1000 game to be released in card form, and the last to be published by Sega, but it is currently unknown as to whether it was the last SG-1000 game. MSX and PC-8801 versions had been released in 1983 and 1984, respectively, meaning this version is unusually late. The game was followed by The Black Onyx II: Search For The Fire Crystal, which saw its original MSX release in 1984.
