Frequently Asked Questions
Quick answers about breaks, checklists, rookie cards, and how Check the Set keeps its data accurate.
- What is a card break?
- A card break is a group event where a breaker opens sealed boxes or cases and divides the contents among participants by team. Check the Set lets you combine multiple sets into a single break view so you can see every team's cards and hits across the products before deciding which spots to grab.
- How do I find a checklist for a set?
- Search for the set by name on the homepage, or use the Browse page filtered by year, sport, or manufacturer. Every set page shows the full checklist organized by subset (base cards, inserts, autographs, relics, parallels) with card numbers, players, and teams.
- What's a 1st Bowman card?
- A 1st Bowman is a player's first appearance on a Bowman prospect card — a flagship Bowman product like Bowman, Bowman Chrome, Bowman Draft, or any of their Sapphire variants. The designation marks the rookie's earliest licensed prospect card, which collectors prize. Check the Set tags 1st Bowman cards explicitly on each set's checklist.
- Are these checklists complete?
- We aim for complete coverage on every flagship release. Each populated set is sourced from the manufacturer's official checklist when one is published; otherwise we use Beckett, Cardboard Connection, Checklist Insider, or TCDB as fallbacks. Sets shown as partial or stub may have missing subsets — that's flagged on the set page and tracked in our update pipeline.
- What does RC mean?
- RC stands for Rookie Card. The card manufacturer (Topps, Panini, Upper Deck, Leaf) decides which players carry the RC designation in each product, and their criteria can differ from MLB/NBA/NFL rookie eligibility rules. Check the Set tags RC cards exactly as the manufacturer does, propagated across every subset within the same product.
- How often is the data updated?
- Released sets are added as soon as the manufacturer publishes a checklist; upcoming sets get a stub entry and are populated when the checklist drops. Our pipeline runs nightly to discover new releases and verify existing data against source pages. New flagship releases typically appear on the site within 1–2 days of being announced.
- Can I share a break with friends?
- Yes. Build a break on the /break page, then click Share — Check the Set generates a URL that encodes the break's name and set list, so anyone with the link sees the same team-by-team breakdown without needing an account. Recipients can save the shared break to their own browser if they want.
- What sports and categories do you cover?
- Sports cards are the focus: baseball, football, basketball, hockey, soccer, plus golf, racing, UFC, and wrestling for major releases. Trading card games (Pokémon, Magic, Yu-Gi-Oh!, Lorcana) and entertainment products (Star Wars, Marvel, Garbage Pail Kids) are covered for flagship releases. We deliberately skip stickers, on-demand singles, and team-specific or one-off promotional products.
