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.
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
