Condition. Inspect chrome refractor surface for scratches, clouding, or print defects; check edges for chipping common in shiny inserts; centering critical for inserts like Ball of Duty.
Storage. Use semi-rigid top loaders with soft sleeves; store in cool, dry environment away from sunlight to prevent refractor fading; avoid stacking without dividers.
Authenticity. Verify Topps hologram and UPC (0610622078907); check serial numbering on parallels like /399; compare print quality to official listings; professional grading recommended for high-value RCs.
