Collector notes

Condition. Check for micro-scratches, handling defects, and surface rayures on the holographic full art; focus on centering, edges, corners, and print quality for grading. Common flaws include surface scratches on holo layer and edge whitening[9].

Storage. Store in sleeves with top-loaders in cool, dry conditions away from sunlight to preserve holo shine; use semi-rigid holders for display.

Authenticity. Verify numbering (252/217 or 282/217), holo pattern, font consistency, and illustrator credit (Narano); use UV light for security features and compare to official scans. Authenticated copies often noted as Near Mint by sellers[2].
