Graded Cards — PSA, BGS, SGC & CGC Certified
Every slab in our inventory is authenticated and graded by an independent third-party service. Grades are final, cert numbers are listed, and pricing reflects the specific grade on the holder — not an approximate condition.
Manna Kingdom carries a curated selection of graded cards and slabs across all major grading services — PSA, BGS (Beckett), SGC, CGC, and CBCS. Every slab is authenticated by the grading company: the grade on the label is the grade we list and price from. We do not accept or resell cracked, tampered, or re-holdered slabs. Our graded inventory spans sports cards (baseball, basketball, football, hockey), Pokémon TCG, Magic: The Gathering, and CGC-graded key issue comics. Raw (ungraded) cards are listed separately under their respective categories with our in-house condition grades. We purchase individual slabs and graded collections — submit a trade-in online or bring your slabs in for a same-day offer.
Graded Cards — Frequently Asked Questions
What grading services do you carry?
We stock cards graded by PSA (Professional Sports Authenticator), BGS/Beckett, SGC, CGC (comic books and cards), and CBCS. Each service uses a different label, holder, and numeric scale. The specific service and cert number are listed on every product page — you can verify directly on the grading company's website before buying.
How do the grade scales work?
PSA and SGC grade on a 1–10 scale (whole numbers only). PSA 10 = Gem Mint; PSA 9 = Mint; PSA 8 = Near Mint–Mint; PSA 7 = Near Mint; grades below 7 indicate visible wear. BGS/Beckett grades 1–10 with half-point increments (e.g., 9.5) and scores four sub-grades (centering, corners, edges, surface). A BGS 10 Black Label requires four perfect 10 sub-grades — extremely rare. CGC uses 1–10 for cards and comics. We price each slab based on its specific grade and current market comps for that exact grade.
Why do graded cards cost more than raw copies?
The price difference reflects three things: (1) independent authentication — a graded slab removes the risk of buying a fake or altered card; (2) condition certainty — the grade is permanently documented, so buyers know exactly what they're getting without trusting a seller's description; (3) liquidity — graded cards with cert numbers have a verifiable market comp. A PSA 10 Charizard and a PSA 7 Charizard are different assets even if the card is the same. We price from recent sold comps on established marketplaces, not arbitrary markups.
What is the difference between a graded slab and a raw card?
A raw card is ungraded — it has been assessed and described by our team using standard condition grades (NM, LP, MP, HP) but has not been submitted to a third-party grading service. Raw cards are less expensive and appropriate for players or collectors who don't require third-party authentication. A graded slab carries a cert number, a permanent numeric grade, and third-party authentication. For high-value cards (generally $100+), grading significantly increases market confidence and resale value.
How do I verify a slab before buying?
Every graded card listing on our site includes the certification number. You can verify authenticity and grade independently: PSA certs at psacard.com/cert, BGS/Beckett at beckett.com/grading/verify, SGC at sgccard.com, CGC at cgccomics.com/certlookup. We encourage buyers to verify before purchasing — legitimate slabs will match exactly.
What grades do you carry, and what grade should I buy?
We carry all grades — from low grades (PSA 1–4) on vintage cards where high grades are nearly impossible, through mid grades (PSA 5–7) for players and budget collectors, up to PSA 9, BGS 9.5, and PSA 10 / BGS 10 for serious investors. For display and collection: PSA 8 or higher. For play/budget: PSA 6–7. For investment/resale: PSA 9 or PSA 10. Grade population (how many of that grade exist) also matters — a PSA 10 from a large modern set is more common than a PSA 9 from a 1999 set.
Do you sell PSA 10 Pokémon cards?
Yes. We stock PSA 10 and BGS 10 Pokémon when available. Vintage sets (Base Set, Jungle, Fossil, Team Rocket) and modern chase cards are a buying priority for our team. Availability changes frequently — follow us on Whatnot or join our newsletter to be notified when high-grade vintage hits the shop.
Do you buy graded cards?
Yes — we buy individual slabs and full graded collections from all major services. Submit a trade-in online or bring your slabs in for a same-day offer. We price from current market comps, not out-of-date price guides. Cash offers and store-credit offers (at a higher rate) are available.
Can a slab be cracked open and the card raw-listed?
We do not crack slabs or resell cracked cards as raw. Every slab we sell is intact as graded. If you want a raw version of a card, check our ungraded inventory. If you want to crack a slab you purchase from us, that is your choice after the sale — but we cannot accept cracked slabs back as returns.
