Not enough observations to draw a history yet. The index records one ratio per pairing per scan; this chart appears once there are at least two.
Every recorded observation
Why these two
Both are rookie cards in the same 220-card set, on the same chrome stock, with the same condition sensitivity that chrome brings. As same-set controls go this is about as clean as the modern era offers.
What would make this wrong
Kobe's market re-rated after his death in 2020. A re-rating is not a cycle, so a ratio measured against it may have found a new normal rather than a temporary gap — and this reading cannot tell the two apart.
How this is measured
Each scan records one number: the fair value of Allen Iverson's 1996-97 Topps Chrome #171 divided by the fair value of Kobe Bryant's 1996-97 Topps Chrome #138, both from comparable sales. The baseline is the median of those observations over 90 days — excluding the most recent 21, so a fresh move cannot drag down the very number it is being measured against. Below 8 observations there is no baseline and this page says so instead of showing one.
The baseline is never authored. It is the median of what was recorded, or it does not exist. Nobody types a target ratio into this system.
This is an observation about a historical relationship, not a forecast. A gap that never closes means the market permanently re-rated Allen Iverson rather than temporarily forgot him — that is the risk in every pairing here, and it does not mean-revert on a schedule.
