Service comparison FAQ

More on BrickGauge vs BrickCheck.

What's the difference between BrickGauge and BrickCheck?

BrickGauge is an AI-driven sealed LEGO pre-grading service — upload six photos, get a six-axis condition score, predicted AFA / CGC grade range, and SEND / MAYBE / HOLD / SKIP verdict in 38 seconds. BrickCheck is a manual authentication service offered by ReUseBricks. BrickGauge is automated, self-service, and free for the first two scans; BrickCheck involves human inspectors and a service request workflow.

Which is better for sealed LEGO authentication — BrickGauge or BrickCheck?

Different functions. BrickGauge provides quantitative six-axis grading prediction with 97.4% reseal-detection recall against 240,127 published grades — calibrated AI output in 38 seconds. BrickCheck provides manual human inspection. For buyer-protection pre-purchase checks: BrickGauge's speed and free tier make it the practical first layer. For high-value disputed authentication: human inspection adds a second opinion layer.

Is BrickGauge free vs BrickCheck?

BrickGauge: two scans free on signup, no credit card. After: $1.50–$2.90 per scan or $29–$199 monthly subscriptions. BrickCheck is a paid service through ReUseBricks; pricing varies. BrickGauge's free tier handles most collectors' one-off authentication decisions.

How accurate is BrickGauge compared to BrickCheck?

BrickGauge matches the published AFA / CGC grade within ±0.5 in 94.2% of audited cases. Reseal-detection recall: 97.4%. The model is calibrated quarterly against fresh AFA / CGC submissions. BrickCheck's manual inspection accuracy depends on inspector experience; ReUseBricks publishes their own service standards.

Can I use both BrickGauge and BrickCheck together?

Yes — they're complementary. Pre-grade with BrickGauge first for the 38-second quantitative six-axis verdict; if the result is MAYBE or you need a second opinion on a $5,000+ transaction, escalate to BrickCheck or a similar manual authentication service. Most authentication decisions don't require the second layer.

Does BrickGauge predict AFA grade like BrickCheck authenticates?

BrickGauge does both: a six-axis condition score (the grading component) and reseal-indicator detection at 97.4% recall (the authentication component). BrickCheck focuses on authentication. BrickGauge's quantitative output includes the AFA / CGC predicted grade range, which BrickCheck's authentication service doesn't typically provide.

Why use AI over manual sealed LEGO inspection?

Three reasons. (1) Speed — 38 seconds vs days. (2) Quantitative output — mm corner compression, % perimeter whitening, sub-3% print drift detection are hard to apply by eye. (3) Calibration — the AI is trained against 240,127 published AFA / CGC grades, so the output maps directly to grader thresholds. Human inspection brings contextual judgment AI lacks; for routine pre-grading, AI is faster and cheaper.
