Authentication: Avoiding Counterfeits

High-value LEGO sets attract counterfeiters. Watch for:

  • Suspiciously low prices: If it's 50%+ below market, it's likely fake
  • Chinese sellers: Most counterfeits originate from China
  • Poor box quality: Blurry printing, incorrect fonts
  • Incorrect logos: LEGO logo should be perfect, not "LEPIN" or "LELE"
  • Plastic quality: Authentic LEGO has specific clutch power and shine

Pro tip: Buy from verified sellers on BrickLink or use authentication services for high-value purchases.
