PCGS vs NGC.

What grading actually is

Coin grading assigns a coin’s condition a number on a 70-point scale (the Sheldon scale). 1 is barely identifiable; 70 is a perfect coin with no imperfections under magnification. The same coin design at different grades can be worth $30 in one grade and $30,000 in another.

Because grading is part objective measurement and part trained eye, two graders can disagree by a point or two. That’s where the third-party grading services come in: an independent, financially-disinterested expert assigns a grade, seals the coin in a tamper-evident plastic holder (a “slab”), and guarantees the grade. Slabbing turns “trust me” into “trust the slab.”

PCGS — Professional Coin Grading Service

Founded 1986, based in Newport Beach, CA. Widely considered the most conservative grader — meaning a PCGS MS-65 tends to be a “solid” MS-65 with no surprises. PCGS slabs are blue-labeled and known for their CoinFacts database and an industry-wide reputation for tight standards.

NGC — Numismatic Guaranty Company

Founded 1987, based in Sarasota, FL. NGC is the official grading service of the American Numismatic Association. Their slabs have a brown / pale label and they’re known for extensive world-coin expertise (including ancients) and a slightly more accessible submission process.

Which slab is worth more?

For most U.S. coins in popular series, PCGS coins trade for a small premium over NGC — a few percent on common dates, sometimes more on key coins or top-population pieces. For world coins and ancients, NGC is often the preferred slab and PCGS-equivalent grades trade at parity or below.

The premium is real but small. Both services are highly trusted by every reputable dealer in the country, and neither is “wrong.” Don’t over-rotate on PCGS vs NGC — what matters most is that the coin is in the right grade, and that the slab is genuine and unaltered.

What about ANACS, ICG, and other slabs?

There are other graders. ANACS is reputable and trades at a small discount to PCGS / NGC. ICG is a legitimate smaller service. Past those two, you start running into “crackable” slabs that the market doesn’t trust — coins inside them are valued as if they were raw. If you have a slab from a service you’ve never heard of, ask before you do anything.

What to do if you have slabbed coins

• Leave them in the slab. Breaking a coin out of a PCGS or NGC holder erases the grade premium instantly.
• Don’t scuff or crack the holder. A scratched slab can require resubmission; a cracked slab voids the grade guarantee.
• Photograph the front of the slab. The label includes the cert number, which we can verify against PCGS or NGC’s online database before any offer.

Should I submit raw coins for grading?

Sometimes — but rarely if you’re about to sell. Grading takes 30–60+ days and costs $20–$80+ per coin. It only makes sense if the coin would jump a meaningful price tier once graded. We can usually tell you whether that’s worth it before you commit any money. The honest answer for most inherited collections is “no, just sell as-is.”
