From your photos to a report.

Four stages with a clear outcome, including when a new capture is needed.

Every report starts with your card.

Original photos. Visible evidence. An independent estimate.

Computer vision and AI, working together.

BGT combines image measurements, capture checks and AI-assisted evaluation. Focus, exposure and geometry help select useful evidence before analysis.

Capture originals underpin the evaluation. Presentation cutouts and reduced-glare viewer images do not replace that evidence.

Our approach draws on techniques studied in computational photography and image analysis. It is an independent BGT estimate: scientific references do not certify product accuracy.

  1. Capture

    Sample artwork. Use your original photos.

    Original photos are the evidence. Catalog artwork cannot replace them.

  2. Prepare & submit

    Review both photos and confirm the evaluation.

    Preparation uses no tokens. An accepted submission reserves 1 G; an identical retry retains the original request.

  3. Evaluate

    Identity and condition answer different questions.

    Which card?
    Identity and printing, when they can be resolved.
    What is visible?
    Visible centering, corners, edges and surface.

    Unresolved identity is not a defect. Reflections and hidden areas limit what can be concluded.

  4. Retrieve

    Follow the status and open the report when available.

    The estimate, observations and limitations remain private. Sharing is a separate action by the owner.

Report completed

The evaluation consumes 1 G. You receive an independent BGT estimate.

1 G consumed

New photos needed

The reservation is refunded. Repeat the requested capture and submit a new evaluation.

1 G returned

Terminal failure

The reservation is refunded. A lost connection alone does not confirm failure: check status first.

1 G returned

Gently dust, dry only

Before taking photos, remove only loose dust and debris with a clean, very soft-bristled brush, without pressing. No water or cleaning products. Do not rub or try to remove stuck-on marks.

  1. Know your card better.

    Best Grading Tools keeps every step simple, from your iPhone to your result.

  2. Review. Save. Or analyse.

    Capture your card and review the photos. Save it without analysis or use a token for a BGT estimate.

  3. Small details deserve a closer look.

    We compare the available photos to locate wear and small marks. Review areas help you inspect them without treating every mark as confirmed damage.

    Keep it in your collection and return to it whenever you need it.

Decide with more context.

The BGT estimate reflects what is visible in the photographs. Lighting, sharpness and finish limit detail; it does not replace physical inspection or certify authenticity.

Your images and reports are private by default. You choose what to share.
