What’s hardest to pull?

Ranked by the largest published “1 in N packs” denominator across this product’s formats. Each card set or parallel appears once, with the format behind that rate. These are odds for a card set, not a specific player or a guarantee of value.

How to read these odds

Published pack odds are Topps’ numbers, shown with their original rate and a plain-language description. A larger pack denominator means a harder pull. A published rate of 3:1 means three cards per pack. These rates apply to a card set or parallel, not a specific player.
Numbering comes from the checklist’s serial-number information. Sets with consistently blank serial numbers are classified as non-numbered. Conflicting or unmatched sets remain unverified; serial numbers in a set name are treated as numbered.
Calculated estimate uses published pack odds and a verified packs-per-box count, assuming packs are independent. Expected copies and the approximate chance of at least one are estimates, not guarantees.
Guaranteed hit is a stated promise. “1 autograph or relic” promises one or the other, not necessarily an autograph.
Multiple published rates for the same set and format are retained in row details. Rankings use the largest denominator; most-common sorting uses the smallest.
Not published / Not confirmed / — mean a verified figure is unavailable. Missing odds do not mean a pull is impossible.
