Anti-Counterfeiting Hierarchy

Professional dealers utilize microscopic and spectroscopic markers to verify slab authenticity. Our taxonomy registers the following verified markers across major companies.

1
UV-Reactive Logos
PSA holders (post-2017) feature a hidden logo visible only under 365nm UV light.
2
Fugitive Ink Patterns
BGS labels use a micro-printing process that smears if high-heat laser printers are used for forgery.
3
Refractive Hologram Threads
CGC labels incorporate a dual-phase hologram thread embedded directly into the paper stock.
SEC
Technical Verification

Validation Checklist

Use these technical checks when inspecting slabs for authenticity. Displacement or deviation from these standards indicates a potential re-case or forgery.

  • Sonic Weld Frosting Consistency
  • Internal Bumper Gap (Standardized at 1.2mm)
  • Label Displacement Limits (< 0.5mm shift)
  • Total Unit Weight Variance (±0.4g)
  • Visual Clarity Index (98%+ Transmittance)
