SPORTS CARD GLOSSARY.

New to the hobby, or just want to double-check a term on one of our listings? Here's a deep-dive glossary covering grading, box and pack formats, group break formats, parallels and inserts, autographs and memorabilia, buying and shipping lingo, and vintage terminology — basketball, football, baseball, and beyond.

GROUP BREAK FORMATS

A cheat sheet for the break formats you'll see called out on our Whatnot shows.

• PYT (Pick Your Team) — Each buyer purchases a specific team (or player/division) spot in advance and keeps every card that team hits during the break.
• Tandem — Two random spots are paired together for the break; whatever either half of the pair hits, both buyers split or share.
• Stash or Pass — When a buyer's team hits, they choose to "stash" the card (keep it for themselves) or "pass" it along, which usually triggers another card to be pulled for the group.
• See 2 Pick 1 — The breaker reveals two teams/spots at once, and the buyer whose turn it is picks one to keep — the other goes back into the pool for later.
• See 3 Pick 2 — Same idea as See 2 Pick 1, but three teams/spots are revealed and the buyer keeps two of the three.
• Immunity — A perk that protects a buyer's spot or hit from a negative break mechanic (like being swapped, stolen, or passed over) for that break.
