⊙ Quick answer

What is grading a sealed LEGO minifigure?

Grading a sealed LEGO minifigure is the process of submitting a factory-sealed polybag minifigure to AFA or CGC for authentication and condition scoring. The six-axis rubric adapts: polybag seal integrity replaces box seal axis; polybag corner condition replaces box corners; polybag scratches and creases replace box surface defects. Eligible submissions are typically SDCC convention exclusives, NYCC exclusives, brand-anniversary promotional polybags, and limited-run themed polybags. AFA 90 premiums range 3–6× over raw on rare exclusives. Fee structure matches sealed-box grading: $23–$40 per submission depending on tier.

Common blind bags

In-production CMF series polybags don't have AFA / CGC graded comp pools. The slab fee exceeds the premium 10× typically.

✕ Skip

Promotional with damage

Polybag creases, ink rub, or seal compromise cap the grade at AFA 80 — where the polybag premium math doesn't work. Pre-inspect first.

Polybag failure modes

What kills a sealed LEGO minifigure grade.

01 Seal compromise

Heat-seal lift

Polybag heat-seal perforations can lift at humidity boundaries. Lifted seals are treated identically to reseal indicators — automatic SKIP.

02 Creasing

Storage compression

Polybags crease easily under stack pressure. Even mild creases cap the grade at AFA 80. Vertical hanging storage is the only protection.

03 Print fade

UV exposure

Polybag print fades under UV faster than box print due to thinner laminate. Sub-3% drift caps AFA 85; visible drift caps AFA 80.

Pre-grade box submissions

BrickGauge for sealed boxes today, polybag coming 2026.

BrickGauge currently optimizes for sealed-box pre-grading. Polybag-specific grading is in 2026 roadmap. For now, pre-grade any sealed boxes alongside your minifigure submissions to maximize the slab-fee math across both. Two scans free on signup.

More on grading sealed LEGO minifigures.

↦Can you grade a sealed LEGO minifigure?

Yes — AFA and CGC accept sealed polybag minifigure submissions, primarily for SDCC, NYCC, and promotional convention exclusives. The rubric adapts: seal integrity becomes polybag seal integrity, corners becomes polybag corner condition, surface becomes polybag scratches and creases. Grading scale is identical to sealed-box LEGO.

↦Which sealed LEGO minifigures are worth grading?

SDCC exclusives (Holiday Train Conductor, Phoenix, Black Manta), NYCC exclusives, brand-anniversary promotional polybags (LEGO House promos, employee gifts), and limited-run themed polybags from major releases (Star Wars Celebration exclusives, Comic-Con Hollywood). Common in-blind-bag polybags don't justify the $25 slab fee.

↦How much does grading a sealed LEGO minifigure cost?

AFA: $25 standard, $40 express. CGC: $23 standard, $30 express. Same fee structure as sealed boxes. Insured shipping $10–$20 each way (lighter than boxes). Total round-trip $45–$80. The AFA / CGC slab for minifigures is smaller than box slabs but uses the same grading scale.

↦What hurts a sealed minifigure polybag grade?

Five things in order of impact: (1) polybag seal compromise — any reseal indicator drops the grade hard; (2) polybag creasing or wrinkles from storage compression; (3) sticker damage on the printed polybag; (4) print fade from UV exposure; (5) sun-yellowing on white or clear polybags. Vertical hanging storage prevents most.

↦What's the AFA 90 premium for a sealed LEGO minifigure?

Depends on rarity. SDCC Holiday Train Conductor polybag at AFA 90 fetches $400–$700 vs $80–$150 raw — a 4–5× premium. NYCC Hulkbuster polybag at AFA 90 $250–$400 vs $60–$120 raw. Brand-anniversary employee polybags can reach $1,000+ at AFA 90 from raw $200–$400.

↦Can BrickGauge pre-grade sealed LEGO minifigure polybags?

Currently the model is optimized for sealed boxes. Polybag-specific grading is in development for the 2026 roadmap. For now, BrickGauge can score the polybag's surface, print, and structural axes from photos with reasonable accuracy; the polybag-seal axis requires specialist inspection.

↦Should I grade my SDCC LEGO minifigure?

If the polybag is pristine (no creases, intact seal, no print fade) and you're holding a $200+ raw comp set: yes. The AFA 85+ premium clears the slab fee on most SDCC exclusives. Pre-inspect under raking light for creases and seal integrity before submitting.

↦What's the difference between grading a sealed box and a sealed polybag?

Same six-axis rubric and grading scale, different specific defects. Boxes get corner compression and edge whitening; polybags get creasing and wrinkle damage. Boxes have rigid seal stickers; polybags have heat-sealed perforations. The investment math is similar — pre-grading still saves the slab fee on borderline submissions.
