Frequently Asked Questions
Everything you need to know about DCM Grading, our three-pass consensus technology, and how to get the most accurate grades for your cards.
Getting Started
#What is DCM Grading?
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.
#How does DCM Grading work?
Simply upload clear photos of your card's front and back. Our DCM Optic™ AI engine performs a comprehensive multi-phase evaluation examining corners, edges, surface condition, and centering.
What makes us unique is our three-pass consensus system — every card is evaluated three independent times, with results averaged and cross-validated. This eliminates errors and ensures the most accurate grade possible.
Within seconds, you'll receive a detailed grade report including component scores, defect documentation, and a confidence rating based on your image quality.
#Why should I use DCM instead of traditional grading services?

Our system automatically detects card type and applies specialized evaluation criteria optimized for each category.
Three-Pass Technology
#What is three-pass consensus grading?
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 all three passes, we average the results and apply consensus rules: a defect must be detected in at least 2 of 3 passes to affect your final grade. This eliminates false positives and ensures only real, verifiable defects impact your score.
This approach mimics how top professional grading companies use multiple human evaluators, delivering the same level of rigor in an automated system.
#Why does three-pass grading improve accuracy?
Reduces Variance: Averaging three independent evaluations produces more consistent, reliable grades than a single pass.
Catches Errors: If one pass misses a defect, the other two passes are likely to catch it.
Eliminates False Positives: By requiring 2+ passes to confirm a defect, we prevent phantom defects from affecting your grade.
Provides Confidence Metric: When all three passes agree closely, you can be highly confident in the grade. Higher variance indicates areas of uncertainty.
#What does the consistency score mean?
The consistency score shows how well all three evaluation passes agreed:
- High Consistency: All 3 passes agree within ±0.5 points — highest confidence in the grade
- Moderate Consistency: Passes vary by 0.5-1.0 points — good confidence, some areas of uncertainty
- Low Consistency: Passes vary by more than 1.0 point — consider resubmitting with better images
Grading Process
#What grading scale does DCM use?
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
#What are component scores?
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 cannot exceed your lowest component score. This ensures consistency with professional grading standards.
#What centering standards does DCM use?
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+)
#What are grade caps?
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
Image Quality
#What is the image confidence rating?
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
#How should I photograph my cards for best results?
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
#Can I grade cards still in sleeves or top loaders?
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.
#Can DCM grade cards already in PSA/BGS/CGC slabs?
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
Accuracy & Comparison
#How does DCM compare to PSA, BGS, and CGC?
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 for informational purposes
Important: DCM grades don't replace official third-party grading for authentication or resale value certification. We're ideal for pre-screening cards before submission or for personal collection management.
#How accurate are DCM grades?
DCM delivers highly accurate grades through several mechanisms:
- Three-pass consensus: Reduces variance and catches errors
- Evidence-based grading: Every deduction requires observable proof
- PSA-aligned criteria: Same standards used by professionals
- Continuous improvement: Our AI learns from millions of evaluations
Accuracy depends on image quality. With Grade A images (clear, well-lit photos), our grades typically align closely with what professional services would assign. Lower quality images increase uncertainty.
#What does "evidence-based grading" mean?
Evidence-based grading means every defect or pristine assessment must be backed by observable evidence in your images. We don't assume defects exist — we only deduct for what we can actually see and document.
For every finding, we record:
- Specific location on the card
- Type and severity of defect
- Measurement or size estimate
- Confidence level in the observation
#What if my DCM grade differs from a professional grade?
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.
Special Cases
#Can DCM grade autographed cards?
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.
#What happens if my card has been altered?
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.
#Does DCM grade vintage cards?
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.
#How does DCM handle error cards and variations?
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.
