Getting cards

Community & culture

Buying Product

  • Hobby vs. Retail – Two different versions of the same product. Hobby boxes go to card shops and online dealers, cost more, and carry better odds and exclusive parallels. Retail goes to big-box stores at a lower price with longer odds. Same brand, same year, very different contents. This trips up more new collectors than anything else on this list
  • Pack – The sealed unit holding a set number of cards. Counts vary widely by product, so always check before assuming
  • Box – A sealed container of packs. Pack counts per box swing dramatically between products, from a single pack in high-end releases to 30 or more in cheaper ones
  • Case – A sealed container of boxes. Most run around 12 boxes, but this varies by product
  • Hobby Box – The version sold through card shops and online dealers. Higher price, better odds, and often parallels you cannot pull from retail
  • Blaster Box – A retail box found at Target and Walmart, usually containing a handful of packs. The most common entry point into the hobby and the one most likely to disappoint someone expecting hobby odds
  • Wax – Catch-all term for sealed, unopened product. "Ripping wax" means opening it
  • Checklist – The full list of every card in a product, from base through every parallel and auto. Usually published before release
  • Pre-Sale – Buying product or singles before the release date. Common and legitimate from established sellers, but you're paying up front for something that doesn't exist yet, so know who you're dealing with

What's Inside a Product

  • Base – The main card set in a product, the cards you pull most often
  • Card set – All cards of a particular type: "I collected the entire base set"
  • Common – A base card of a non-notable player. The opposite of a hit, and the bulk of what comes out of any box
  • Insert – A separate themed set inserted alongside the base, with its own name, design, and numbering
  • Parallel – A version of an existing card distinguished by color, finish, or serial numbering
  • Rainbow – Every parallel of a single card. "Chasing the rainbow" is the pursuit of completing one
  • RC – Rookie Card
  • Hit – Any auto, relic, or notable numbered card. The cards you're actually opening the box for. Products often guarantee a set number of hits per box
  • Non-Licensed – The manufacturer has rights to the player but not the league, so team logos and uniforms are edited out. These typically carry less value than fully licensed cards of the same player

Storing & Protecting

  • Penny Sleeve – A thin, cheap plastic sleeve. Named for roughly what one costs. The first thing that goes on any card worth keeping
  • Toploader – A rigid plastic holder. Standard practice is penny sleeve first, then toploader, especially for shipping or storage
  • Dinged – Damaged. Usually refers to a bent or blunted corner, but also covers surface scratches and edge wear. A dinged card will not grade well

Card Types & Construction

  • Card Stock – The material a card is printed on. Thickness and finish vary by product, with premium releases generally using heavier stock
  • Chrome vs. Paper – Chrome cards are printed on a reflective chromium stock, giving them a metallic look and a stiffer feel than standard paper cards. Chrome versions of a set usually carry more value and are the basis for refractor parallels
  • Refractor – A chrome parallel with a prismatic finish that catches light. Most products run a full ladder of colored refractors, each at a different print run
  • Superfractor – The rarest refractor, always a 1/1. In Topps and Bowman Chrome it sits at the top of the parallel ladder
  • Variation (VAR) – A card that differs subtly from its standard counterpart: an alternate photo, a different background, a corrected error. Variations are typically short printed and can be worth far more than the base version
  • Die-cut – A card with part of the stock cut away to create a shape. Usually used for inserts and usually short printed
  • Printing Plate – The metal plate used to print the cards, offered as a collectible. They come in cyan, magenta, yellow, and black, and each is a 1/1
  • Book Card – Two or more cards joined so they open like a book, typically holding autos or memorabilia
  • Sketch Card – A hand-drawn, one-of-one card created by a licensed artist and usually signed. Most common in non-sports products
  • Rookie Cup – A trophy logo Topps places on the following year's card of players named to its All-Star Rookie Team. Brand-specific to Topps, but you'll see the trophy and wonder what it means

Rarity & Print Runs

  • Serial – The numbering on a card, e.g. "11/150"
  • Numbered vs. Jersey Number – A card numbered /25 has 25 copies. A jersey-numbered card is serial numbered to match the player's uniform number, which makes that one copy in the run more desirable
  • SP – Short Print
  • SSP – Super Short Print, seeded at much longer odds than an SP
  • Case Hit – Roughly 1 per case, though some fall closer to 1 per several cases
  • 1/1 – One of one, the single rarest version of a card

Autographs & Memorabilia

  • RPA – Rookie Patch Auto
  • On-Card Auto – The signature is written directly on the card, usually more desirable than a sticker auto
  • Sticker Auto – The signature is on a clear sticker applied to the card
  • Inscription – Extra text a player adds alongside their signature: a nickname, a stat, a Hall of Fame year. Usually adds value
  • Relic / Patch / Jumbo – Memorabilia cards, in ascending order of desirability. A relic is usually a small single-color swatch, a patch has multiple colors or stitching, and a jumbo is an oversized piece
  • Game-Used / Game-Worn / Player-Worn / Event-Worn – The provenance ladder, strongest to weakest. Game-used covers equipment actually used in a professional game, and game-worn means the item was worn in an official game. Player-worn means the player wore the item at some point but not in a game, sometimes only briefly for the purpose of creating memorabilia. Event-worn narrows that to a specific non-game event like a photo shoot or signing session. The wording on the back of the card is doing real work here, and the difference between game-worn and player-worn can be a large gap in value
  • Logoman – A card containing the team logo patch from a jersey. Only one exists per jersey, so these are always 1/1 and among the most valuable cards in the hobby
  • Redemption – A card that isn't in the pack yet. You enter a code online and the manufacturer mails you the real card once the player signs. Waits can run months or years, and some never get fulfilled

Grading & Condition

  • Raw – An ungraded card, fresh out of the pack
  • Slab – A graded card sealed in a hard plastic case. "Slabbing" is used interchangeably with grading
  • PSA – Professional Sports Authenticator, the largest third-party grading and authentication company
  • BGS / SGC / CGC – The other major graders. Beckett (BGS) is known for subgrades and the Black Label 10, SGC for its black-matted slab and fast turnaround, CGC for its comics roots and growing card business
  • Gem – A card that receives the top grade, e.g. PSA 10 Gem Mint
  • Subgrades – Grades for individual dimensions: centering, surface, edges, corners
  • Auto 10 – Only the autograph is graded. Common for in-person autos, or used to add value to a card that would not grade well overall
  • Pop Report – A grading company's public census of how many copies of a card have received each grade. The fastest way to judge whether a graded card is actually scarce

Breaks

  • Breaks – Buying a portion of a box/case shared with others (Teams / Divisions / Players / Random)
  • Group Break vs. Personal – A group break splits one box or case among many buyers. A personal is one buyer paying for the whole thing and having a breaker open it on stream
  • Slot / Spot – The share you buy into a break
  • PYT – Pick Your Team
  • PYP – Pick Your Player
  • Random Team / Player / Serial – You get assigned a spot randomly once the break fills
  • Givvy – Giveaway

Collecting Styles

  • Player Collecting – Chasing every card of one athlete: base, parallels, inserts, autos, the whole history
  • Team Collecting – Building around a single franchise across sets and years
  • Set Collecting – Completing every card on a product's checklist. A completist goes further and chases every parallel and auto too
  • Prospecting – Buying cards of players who haven't reached the majors yet, betting on who breaks out. The core of Bowman collecting
  • Vintage – Collecting older cards, generally pre-1980, though the cutoff is debated

Shows & Slang

  • LCS – Local Card Shop
  • Card Show – A trade show where collectors and dealers buy, sell, and trade in person. Hundreds happen annually across the country
  • The National – The National Sports Collectors Convention, the largest card show of the year and the hobby's biggest annual gathering
  • PC – Personal Collection
  • Grail – Dream card
  • Junk Wax Era – The late 1980s through early 1990s, when manufacturers massively overproduced. It's why a shoebox of 1990 cards is usually worth almost nothing, and it explains a lot of misplaced expectations about old cards
  • RAK – Random Act of Kindness

Back to top

Bowman & Prospecting

  • "1st" – Designates a player's first Bowman card, released before their official rookie card. The card must carry the 1st Bowman badge in the corner
  • True Color / True Refractor – The standard version of a parallel, matching the base card's photo and layout rather than a patterned or alternate variation. A Blue Refractor is the true color; a Blue Wave or Blue Shimmer is not. Most collectors seek the true version, and it typically carries a premium over the patterned variants at the same print run
