Saves Roberto Clemente's 1955 Topps #164 (ungraded) to your watchlist, where the daily scan flags listings priced under that card's own comparable sales. That is a different question from this board: the watchlist will not tell you when this ratio moves, and nothing here alerts on the gap.

Why these two

A same-decade Topps rookie — Clemente #164, a high-number card in the 1955 set — measured against the benchmark card of the era.

What would make this wrong

Same trophy-asset problem as any pairing against the 1952 Mantle, plus a thin 1955 high-number comp pool where a single sale can set the month's number. Measured ungraded for the same reason as the Aaron pairing — the guide has no grade-4 tier to resolve.

How this is measured

Priced on ungraded (raw) copies, the grade this pairing names.

Each scan records one number: the fair value of Roberto Clemente's 1955 Topps #164 (ungraded) divided by the fair value of Mickey Mantle's 1952 Topps #311 (ungraded), 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 Roberto Clemente rather than temporarily forgot him — that is the risk in every pairing here, and it does not mean-revert on a schedule.
