Understanding Card Grading: PSA, MGC, and Beckett Explained

Grading and authentication play a vital role in today’s collectibles market. For buyers and sellers alike, third-party grading provides clarity, trust, and confidence.

Several grading companies are widely recognised within the hobby, each with their own processes and areas of expertise. At Blooms Auction, we work with authenticated items from leading grading and authentication companies to ensure transparency and buyer confidence.

What Does Card Grading Do?

Card grading is the independent assessment of a collectible’s authenticity and condition.

A graded card is evaluated for factors such as centring, corners, edges, surface quality, and overall preservation. Once assessed, the card is encapsulated in a tamper-evident holder with a clearly defined grade.

This process protects the item, standardises condition, and provides buyers with confidence when bidding.

PSA (Professional Sports Authenticator)

:contentReference[oaicite:0]{index=0} is one of the most established grading companies in the collectibles industry.

PSA is widely known for grading sports cards, trading cards, and memorabilia-related items.

Their grading process focuses on:

• Authenticity verification
• Condition assessment using a numerical scale
• Secure encapsulation for long-term protection

PSA-graded items are commonly traded globally and are familiar to collectors and investors worldwide.

Majesty Grading Company (MGC)

MGC specialises in trading cards, sports cards, and collectible assets, offering detailed assessment, consistent grading, and high-quality encapsulation.

MGC places strong emphasis on transparency, accuracy, and presentation, making their graded items clear and accessible to buyers.

Beckett Grading Services (BGS)

Beckett is known for its detailed subgrades, which break down specific aspects of a card’s condition such as corners, edges, surface, and centring.

This additional detail can be particularly valuable for collectors who want deeper insight into an item’s condition.

How Blooms Auction Works with Graded and Authenticated Items

Blooms Auction is grader-agnostic. We focus on authentication, transparency, and buyer confidence rather than favouring a single grading provider.

Items graded or authenticated by recognised grading companies are accepted for auction, provided they meet suitability criteria and align with upcoming sale themes.

All items are reviewed internally to ensure accurate representation and clear presentation to bidders.

Why Grading Benefits Auction Sellers

Graded and authenticated items consistently perform well at auction due to increased buyer confidence.

Clear verification reduces uncertainty, encourages participation, and often results in stronger competitive bidding.

This applies across Pokémon cards, sports cards, and other graded collectibles.

Authentication, Not Hype

At Blooms Auction, our priority is trust.

By working with established grading and authentication companies, we ensure buyers know exactly what they are bidding on and sellers can feel confident their items are positioned correctly.

Fees and Transparency

Buyer’s Premium

A buyer’s premium of 20% is applied to the final hammer price and paid by the buyer.

Seller Fees

Blooms Auction offers 0% seller fees, meaning sellers receive the full hammer price achieved at auction.

Seller Payment Timeline

Following a successful sale, sellers are paid once the agreed post-auction waiting and cooling-off period has passed.

This ensures buyer settlement is complete and provides a secure, compliant transaction for all parties.

Thinking of Selling a Graded Collectible?

If you own a graded Pokémon card, sports card, or authenticated collectible, auction may be an effective way to unlock its true market value.
