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
Adjacent-year rookies from the same product line — McGrady #125 in the 1997-98 set, Kobe #138 in the 1996-97 — bought by the same collectors for the same era.
What would make this wrong
Different sets a year apart, so the ratio also moves on set-level supply and grading population, not only on the two players. Read it as context rather than as signal.
How this is measured
Each scan records one number: the fair value of Tracy McGrady's 1997-98 Topps Chrome #125 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 Tracy McGrady rather than temporarily forgot him — that is the risk in every pairing here, and it does not mean-revert on a schedule.
