CardZ Marketcap graded card glossary
- Market cap (trading card)
- The PSA 10 reference price of a printing multiplied by its verified PSA 10 population. It measures the total value of top-grade supply, not the price of a single copy.
- PSA 10 market cap
- Market cap computed strictly from PSA 10 inputs: the price of a PSA 10 copy and the count of PSA 10 copies. Lower grades are excluded from the figure.
- PSA
- Professional Sports Authenticator, a third-party grading company. PSA assigns a numeric grade to a submitted card and publishes population counts for each grade.
- PSA 10
- PSA's highest standard grade, described as Gem Mint. It is the grade CardZ Marketcap uses for both the price and the supply side of market cap.
- Population report
- PSA's published count of how many copies of a card it has graded at each grade. It is the source of the supply term in market cap.
- Pop
- Short for population. Pop 10 means the number of copies graded PSA 10 for a specific printing, set, language and finish.
- Reference price
- The price CardZ Marketcap holds for one PSA 10 copy of a printing on a given date, derived from graded-sale evidence for that exact printing.
- Printing
- A specific release of a card: one set, card number, language and finish. Different printings of the same artwork are ranked as separate rows.
- Finish
- The surface treatment of a card, such as holo, reverse holo or non-holo. Finish changes both scarcity and price, so it is part of a printing's identity.
- Parallel
- An alternate version of a card printed with a different treatment or numbering. Parallels have their own populations and prices and never share a market cap row.
- Promo
- A card distributed outside standard set packs, such as an event or campaign card. Promos often carry small populations and volatile prices.
- Set code
- The short identifier for the set a card belongs to. Combined with the collector number it identifies which printing a price and population belong to.
- Collector number
- The number printed on a card showing its position within a set, such as 085/SVP. It is part of how a printing is matched to its population data.
- Grading
- The process of submitting a card for third-party assessment of centring, corners, edges and surface, resulting in an encapsulated card with a numeric grade.
- Gem rate
- The share of submitted copies that receive a PSA 10. A low gem rate means PSA 10 supply grows slowly even when many copies are submitted.
- Raw
- An ungraded card. Raw copies have no verified supply count, which is why they are not used for market cap.
- Ungraded reference price
- An indicative price for a raw copy, shown for context only. It never enters the market cap calculation.
- Slab
- The sealed plastic holder a graded card is encapsulated in, carrying the grade and a certification number.
- Certification number
- The unique number assigned to a graded card. It identifies one physical slab rather than a printing.
- Crack and resubmit
- Removing a card from its slab and submitting it again for a higher grade. It can cause the same physical card to be counted more than once in population data.
- Verified supply
- The portion of a card's supply that has been counted by a grading company. CardZ Marketcap uses verified supply rather than estimated print runs.
- Print run
- The number of copies originally produced. Print runs are rarely published for trading cards and are not used in this index.
- Graded card market index
- A ranking of cards by a value measure computed from graded data. CardZ Marketcap is a graded card market index built on PSA 10 price and population.
- Snapshot
- A single published build of the index, identified by a generation and an effective date. Every figure on the site belongs to one snapshot.
- Effective date
- The date a snapshot's figures represent. It is shown on every page so a quoted figure can be tied to a specific day.
- Observation date
- The date a specific price or population was observed. It can be earlier than the effective date when a source has not moved.
- Accumulating
- A status shown when there is not yet enough evidence to publish a value. It means the figure is being collected, not that the value is zero.
- Stale
- A status shown when a value exists but its observation date is old. The number is still displayed, with its date, rather than being hidden.
- Coverage
- How complete a snapshot is relative to what it claims to rank. Coverage is published with each snapshot so gaps are visible.
- Watchlist
- Ranked printings outside the top 100 that are tracked with the same method. They use identical inputs and appear in the same totals.
- One Piece Card Game
- The trading card game based on the One Piece manga. Its graded printings are ranked alongside Pokémon using the same market cap method.
CardZ Marketcap is a trading card price index. It is not a cryptocurrency, not a token, and not a listed company. There is no CardZ ticker, and this site is unrelated to the crypto asset traded as CARDS.
