A Pokemon mystery slab is one random encapsulated graded Pokemon card, and an advertised floor price does not tell you what your pull will resell for. The floor describes only that seller's defined batch, card pool, grades and price measure, so the same dollar figure can mean very different cash outcomes. Shiny Vert offers mystery tiers with different minimum grades and random era, set and English-or-Japanese language. Photos may show possibilities rather than guaranteed contents, so buyers should read the batch terms before treating the floor as protection.

What do you actually receive?
You receive one random slab selected by the seller, not a chosen card. Shiny Vert lists tiers such as Poke Tier and Great Tier with varying minimum grades and random era, set and language, according to the Shiny Vert store page.
The same category commonly allows wide grade and grader variation. Shiny Vert disclosures include minimum grade 5 for vintage cards and slabs graded 8-10, with photos stated to show possibilities rather than guaranteed contents.
Why does a floor belong to one batch?
A floor applies only to the exact pool the seller defined. Pokemon Plug advertised a $20 floor, $220 ceiling and $36.19 average across 20 exact PSA 10 Japanese art-rare cards, with 1:21 odds for a Charizard ex SAR, according to the Pokemon Plug official product page.
That structure means the $20 figure does not transfer to another seller, tier or restock. A different mix of cards, grades, graders, languages or odds creates a different floor and average.
Why is the same grade number not the same value?
Graded-card value needs same-card, same-grade, same-grader comparison. PriceCharting says it updates prices from listings that actually sold on eBay and other marketplaces, separately by grade, according to the PriceCharting methodology notice. Market Price is also different from asking prices.
TCGplayer Help Center says TCGplayer Market Price is compiled from multiple recent completed TCGplayer sales and updated as transactions complete, according to the TCGplayer Market Price article. An advertised floor based on active asks can therefore exceed cash realized in sold transactions. eBay reporting notes its card tool shows up to two years of sales data and lets users compare sold versus active listings.
What should you check before buying?
Read the listing as a batch contract, not as a price guarantee. Confirm the included set list, grade range, graders, language mix and odds.
PSA authentication and encapsulation carries a separate per-card fee, with Regular service listed at $79.99 per card up to $1,500 insured value and 70-80 business days. In January 2025 the FTC required Genshin Impact maker Cognosphere to pay $20 million and avoid misrepresenting loot-box odds and costs, a reminder to keep seller odds and cost claims in writing.
- Write down the exact eligible cards and grades for your tier.
- Check sold prices for the same card, grade and grader.
- Compare sold results against active asks for the weakest likely pulls.
- Treat grading fees and shipping as sunk cost, not resale value.
- Save the odds, floor definition and photos disclosure before paying.
