The 3X Rule: When Grading Pays Off

Professional collectors only submit coins when the certified value exceeds the raw value by at least 3X the grading fee.

Minimum Value Increase

If grading doesn't add at least $120 in value, you lose money after fees, shipping, and insurance.

Most collectors overestimate their coin's grade by 1-2 points

That's why pre-screening with AI saves hundreds in wasted grading fees every year.

Should You Grade Your Coin?

DO Grade These Coins

  • High-grade modern coins (MS-67+) where grading adds significant value
  • Key dates or rare varieties worth $200+ raw
  • Coins with exceptional eye appeal or unique toning
  • Borderline gem coins (MS-64/65) with strong market demand
  • Coins where authentication alone adds value (counterfeit concerns)
  • Coins that pass the 3X rule after AI pre-grading

DON'T Grade These Coins

  • Common-date coins in circulated condition (below AU-55)
  • Coins with visible cleaning, damage, or corrosion
  • Low-value coins where the fee exceeds raw coin value
  • Modern bullion coins without special designations (unless MS-70)
  • Coins that fail the 3X rule (certified value won't justify fees)
  • Coins with low AI confidence scores indicating borderline or problem coins
