Pack Odds Lookup

Choose the box format your pack came from, then choose the card or chase type you care about. The lookup uses the format-specific Topps pack odds and shows what is in one pack plus your chances from that exact pack source.

Your odds depend on both choices below

First pick the box your pack came out of. Then pick the card, insert, parallel, auto, or chase type you want to check.

Changing either dropdown updates the odds

Step 1 Choose pack or box odds Look at one loose pack, or all packs inside the box.

Step 2 Pick the box your pack came from Value, Mega, Hobby, Hanger, Fanatics, etc. can have different pack odds. Step 3 Pick the card or chase type Choose the specific base, parallel, insert, auto, or chase category.

Production Distribution

How the estimated product print run breaks down by type when total production data is loaded. Base cards usually make up the largest share, while inserts, autos, and numbered parallels are a much thinner slice.

Format Comparison

Compare product formats by pack configuration, cards per box, autos, parallels, prices, and estimated production when that data is available.

Numbered Auto Rate by Format

For products with normalized autograph data, this shows what percentage of pulled autos are numbered rather than unnumbered base versions.

Base Card Print Runs

Veteran Base is massively overprinted at ~383K per card. Rookie Chrome Base at ~15K is the scarcest base type — roughly 25× rarer.

Numbered Parallel Rainbow

16 tiers from Coral /299 down to the 1-of-1 Superfractor. This is an unusually deep rainbow — most Topps products have ~10 tiers.

Unnumbered Parallels

No serial number, but scarcity varies dramatically. Yellow parallels at ~400 copies are stealth hits — as rare as some numbered cards.

Insert Sets by Rarity

13 insert sets ranging from common (~18K/card) to extremely scarce (~145/card for Hobby-exclusives). The "per card" count is how many copies of each individual card in the checklist exist.

Autograph Sets by Rarity

For a product called "Signature Class," the auto landscape is bottom-heavy. Most are unnumbered base versions. Dual and Triple autos at 15–20 copies per card are the true needle-in-a-haystack pulls.

Official Topps Odds Sheet

Pick a product format to translate Topps pack odds into estimated per-box hit probability. This is the source-of-truth odds layer we can expand into a full imported database.

Subset	Type	Pack Odds	Box Probability	Avg Boxes	Avg Cost

Import path: Topps product page -> linked checklist/odds PDFs -> normalized product, format, subset, parallel, and odds tables. This page now models that end state with static data for the first set.

Odds Calculator by Format

Select a box format to see per-box hit rates, cost per hit type, and a chase cost estimator showing how many boxes and dollars it would statistically take to pull specific rare cards.

🗄️ Future: Database Integration
This dashboard currently runs from static data. The architecture is ready for a MySQL/MariaDB backend — the PRODUCT_DATA object maps directly to normalized tables (products, formats, cards, parallels, inserts, autos). When you're ready to add more products, we'll swap the data source from this JS object to API calls.
