The big two: PCGS and NGC
PCGS (founded 1986) and NGC (1987) dominate the market and enjoy the strongest price acceptance — coins in their holders routinely sell for more than the same coins in other holders. Both back their grades with guarantees, run population reports showing how many coins they have graded at each level, and offer online certificate verification.
Between the two, market preference varies by series and region; both are fully liquid. For world coins NGC has particular strength, while PCGS often leads registry-set pricing for classic US material.
ANACS, ICG, and everyone else
ANACS (the hobby’s oldest service, with roots in the ANA) and ICG are legitimate graders whose holders trade at some discount to PCGS/NGC — buyers often treat their grades a shade more skeptically. They are popular for variety attribution and for lower-value coins where big-two fees do not pencil out.
Beyond these four, dozens of small or self-styled grading companies exist whose slabs carry little or no market weight; some are outright deceptive, slabbing overgraded or counterfeit coins. As a rule, price a coin in an off-brand holder as if it were raw.
Costs and the submission process
Fees are per coin and scale with declared value and turnaround speed: economy tiers for modern coins commonly run in the range of roughly $20–40 per coin, with vintage and high-value tiers costing more, plus shipping and insurance both ways. Both big services require a membership or authorized-dealer submission.
The process: you (or a dealer) submit coins in approved flips, the service authenticates, grades, encapsulates, and returns them, with results posted online. Turnaround runs from days on express tiers to months on economy tiers in busy periods.
When grading pays — and when it does not
Certification pays when it raises a coin’s sale price by more than its all-in cost: rare dates, better-grade type coins, gold, and anything where authenticity doubt suppresses raw value. It does not pay on common circulated coins, most moderns, or cleaned pieces destined for details grades.
- Grade: key dates, coins likely worth a few hundred dollars up, and coins you plan to sell
- Skip: bullion-value silver, common wheat cents, circulated moderns, damaged coins
- Borderline: submit only after honestly pre-grading — hope is not a grading strategy
Pre-screen submissions with CoinVault Pro
The costliest grading mistake is paying fees for coins that come back in cheap grades. CoinVault Pro’s AI gives every coin a Sheldon-scale estimate from a photo, paired with live sold prices at that grade — so you can see whether the certification math works before mailing anything.
Track submitted coins in your collection manager and update their records with final grades when results post.
