Frequently Asked Questions

DCM Grading is an AI-powered card grading service that provides professional-quality condition assessments for trading cards. Using our proprietary DCM Optic™ technology, we analyze your card images and deliver accurate grades in under 60 seconds.

Unlike traditional grading services that can take weeks or months, DCM provides instant results while maintaining the same rigorous standards used by professional grading companies.

Upload clear photos of the front and back of your card. DCM Optic™ examines corners, edges, surface, and centering on both sides.

Then it does it twice more. Our three-pass consensus system evaluates every card three independent times and averages the results. A defect has to show up in at least two of the three passes to affect your grade, which keeps false positives out and produces a more stable grade than any single pass would.

You get a full grade report in seconds, including component scores, marked defects, and a confidence rating tied to your photo quality.

Speed: Results in under 60 seconds, not weeks or months.

Cost: A fraction of what mail-away grading costs.

Convenience: Grade from anywhere. No shipping, no insurance, no return label.

Accuracy: Three-pass consensus produces consistent, repeatable grades.

Transparency: Every grade comes with defect documentation. You can see exactly why your card scored what it did.

DCM supports a wide variety of trading cards:

• Sports Cards: Baseball, Basketball, Football, Hockey, Soccer, Wrestling, UFC, and more
• Pokémon: All sets including Japanese, Promos, Full Art, and vintage
• Magic: The Gathering: All sets, foils, borderless, and special editions
• Disney Lorcana: All sets and rarities
• Other TCGs: Yu-Gi-Oh!, One Piece, and other collectible card games

Our system automatically detects card type and applies specialized evaluation criteria optimized for each category.

Three-pass consensus grading means every card is evaluated three complete, independent times. Each pass examines all corners, edges, surface, and centering as if seeing the card for the first time.

After the three passes, we average the results and apply a consensus rule: a defect has to be detected by at least 2 of 3 passes to count against your grade. This keeps phantom defects out and only real, verifiable issues affect your score.

It's the same approach top grading companies use when they put multiple human graders on a single card, just automated.

Reduces variance: Averaging three independent evaluations gives you a more stable grade than any single pass.

Catches misses: A defect that one pass missed will usually get picked up by the other two.

Filters phantom defects: Requiring two of three passes to agree keeps false positives out of your grade.

Tells you when to trust the grade: When all three passes agree closely, you can trust the result. When they diverge, the confidence score warns you.

The consistency score shows how closely the three evaluation passes agreed:

• High consistency: All 3 passes within ±0.5 points. Trust the grade.
• Moderate consistency: Passes vary by 0.5-1.0 points. The grade is solid but there's some judgment-call territory.
• Low consistency: Passes vary by more than 1.0 point. Worth resubmitting with better photos.

DCM uses a 10-point scale with 0.5 precision, aligned with industry-standard grading criteria:

• 10: Gem Mint — Zero defects, perfect in every way
• 9.5: Gem Mint — Near-perfect with only microscopic imperfections
• 9: Mint — Minor imperfections under close inspection
• 8.5-8: Near Mint-Mint — Slight wear visible upon examination
• 7.5-7: Near Mint — Minor wear visible at normal distance
• 6.5-6: Excellent-Mint — Visible wear but displays well
• 5.5 and below: Varying degrees of wear or damage

Every card receives 8 individual component scores — 4 for the front and 4 for the back:

• Centering: Border distribution and alignment
• Corners: Sharpness, fiber exposure, structural integrity
• Edges: Whitening, chipping, factory cut quality
• Surface: Scratches, print defects, stains, structural damage

Front and back are weighted 55%/45% respectively, with the front given more weight as it's the primary display side.

Weakest Link Rule: Your final grade can't exceed your lowest component score, matching how PSA, BGS, and SGC assign final grades.

DCM uses PSA-aligned centering standards:

• Front: 55/45 or better required for Gem Mint 10
• Back: 75/25 acceptable (weighted less heavily)

Centering is measured as a ratio (e.g., 60/40) where a perfect card would be 50/50. The first number represents one side, the second represents the opposite side.

Quality tiers: Perfect (50/50-51/49), Excellent (52/48-53/47), Good (54/46-55/45), Fair (56/44-60/40), Off-Center (61/39+)

Grade caps are automatic limits applied when structural damage is detected. Certain defects are so significant that they limit the maximum possible grade regardless of how perfect other areas are.

Examples of grade-capping defects:

• Creases (visible fold lines)
• Corner lift or tilt (corner separating from surface)
• Tears or paper loss
• Severe bends affecting card structure

The confidence rating (A-D) indicates how well we can assess your card based on image quality:

• Grade A (95-100% visibility): Crystal clear images, highest confidence, ±0.25 uncertainty
• Grade B (85-94% visibility): Clear images with minor issues, high confidence, ±0.5 uncertainty
• Grade C (70-84% visibility): Acceptable images with moderate issues, ±1.0 uncertainty
• Grade D (<70% visibility): Significant issues, consider resubmitting, ±1.5 uncertainty

For the most accurate grades, follow these tips:

• Use natural lighting or bright, diffused artificial light
• Avoid flash — it creates glare that obscures defects
• Keep the card flat and parallel to the camera
• Remove from holders/sleeves when possible
• Fill the frame with the card, minimal background
• Ensure the entire card is in sharp focus
• Use a solid, contrasting background color
• Capture both front AND back images

Yes, but with some caveats:

• Penny sleeves: Usually fine, may slightly reduce confidence
• Top loaders: Acceptable, watch for glare on the plastic
• Thick holders/slabs: More challenging due to reflections and distortion

For best results, remove the card from its holder if you can do so safely. Cards in holders typically receive a B or C confidence rating due to visibility limitations.

Yes! DCM Optic™ can detect professionally graded slabs and perform an independent assessment. We'll identify the grading company and existing grade, then provide our own evaluation.

Keep in mind:

• Slab plastic may create glare or reflections
• Image confidence will typically be B or C
• Our grade is independent and may differ from the slab grade
• We note visibility limitations in our analysis

DCM uses grading criteria aligned with professional services like PSA, BGS, and CGC. Our three-pass consensus system mimics how these companies use multiple human evaluators.

Key differences:

• DCM grades are based on photo analysis, not physical inspection
• DCM is instant; traditional services take weeks/months
• DCM costs a fraction of traditional grading fees
• DCM grades are professional condition assessments

Important: DCM grades are an independent evaluation of your card's condition based on our proprietary standards. Many collectors use DCM for collection management, marketplace listings, and as an alternative to traditional mail-away grading.

A few things keep DCM grades tight:

• Three-pass consensus: Reduces variance, catches single-pass errors.
• Evidence-based grading: Every deduction is backed by an observable defect, not an assumption.
• PSA-aligned criteria: The same standards professional graders work from.
• Continuous improvement: The model is regularly retrained on new card sets and edge cases.

Accuracy is bounded by your photo quality. Grade A images (clear, well-lit, in focus) produce grades that align closely with what professional services would assign. Blurry or poorly-lit photos widen the uncertainty range.

Evidence-based grading means every defect we call out has to be backed by something visible in your photos. We don't assume; if we can't see and document it, we don't deduct for it.

For every finding, we record:

• Specific location on the card
• Type and severity of defect
• Measurement or size estimate
• Confidence level in the observation

Grade differences can occur for several reasons:

• Image limitations: Photos may not capture all defects visible under physical inspection
• Subjectivity: Even professional graders can vary by ±0.5 points on the same card
• Different standards: PSA, BGS, and CGC have slightly different criteria
• Timing: Grading standards can shift over time

Use our uncertainty range as a guide. A card graded 9.0 with ±0.5 uncertainty could reasonably receive an 8.5-9.5 from a professional service.

Yes, but with important distinctions:

• Manufacturer-authenticated autographs: Cards with official autograph certification (hologram, printed authentication) are graded normally. The autograph is noted as a special feature.
• Unverified signatures: Cards with signatures that aren't manufacturer-authenticated receive an "N/A" grade because we cannot verify authenticity.

We look for authentication markers like holograms, "Certified Autograph Issue" text, and official autograph card numbering.

Cards with post-production alterations receive an "N/A" (Not Authenticated / Altered) designation instead of a numeric grade. Alterations include:

• Trimmed edges or borders
• Unverified autographs or markings
• Handwritten additions (names, dates, prices)
• Adhesive residue or sticker damage
• Color enhancement or restoration

We still provide a full analysis explaining what was detected and why the card cannot receive a numeric grade.

Yes! DCM can grade vintage cards from any era. Our system accounts for:

• Different printing and cutting standards from various decades
• Era-appropriate expectations for centering and edges
• Common vintage defects like wax staining or gum residue
• Manufacturing variations that aren't defects

High-quality photos are especially important for vintage cards to capture subtle wear patterns and distinguish age-related characteristics from damage.

DCM recognizes and documents error cards and variations. Manufacturing errors that occurred during production (misprints, wrong backs, missing foil, etc.) are noted as special features, not defects.

The condition grade reflects the physical state of the card, not whether it's an error. An error card can still be Gem Mint if it has no wear or damage.

DCM uses a credit-based system. Credits can be purchased in packages:

• Each card grade costs 1 credit
• Re-grading a card (with new photos) costs 1 credit
• Bulk packages offer significant savings

Visit our Credits page for current pricing and packages.

New accounts receive complimentary credits to try the service. This lets you experience DCM Grading before purchasing additional credits.

Yes! If you're not satisfied with your grade or want to try with better photos, you can re-grade any card in your collection. Re-grading costs 1 credit and performs a fresh three-pass evaluation.

Re-grading is recommended when:

• Your original images had glare or blur
• You received a low confidence rating (C or D)
• You want to verify the grade with different lighting

All your graded cards are saved in your Collection. You can view detailed reports, download grade certificates, share cards publicly or keep them private, and track your collection's overall condition distribution.

You control the visibility of each card:

• Public: Card is searchable and viewable by anyone with the link
• Private: Only you can see the card when logged in

You can change visibility at any time from the card detail page.

DCM accepts JPEG, PNG, HEIC, and WebP images. For best results, use high-resolution photos (at least 1000x1400 pixels) with good lighting and minimal compression.

Yes! DCM is fully mobile-friendly. You can take photos directly with your phone camera and upload them immediately. Modern smartphone cameras produce excellent results when using proper lighting.

Most cards are graded in 30-60 seconds. Complex cards with many features or special finishes may take slightly longer. You'll see a progress indicator while your card is being analyzed.
