PCGS vs. NGC: Which Grading Service Should You Trust?
PCGS and NGC are both legitimate, widely accepted third-party coin grading services, and for the certified bullion coins we carry — MS69/MS70 and PR70/PF70 graded Eagles across gold, silver, and platinum — the practical difference between them is minimal. Both use the same 1-to-70 numerical scale, both encapsulate coins in tamper-evident holders, and both are trusted by dealers and collectors worldwide. The gap that does exist between them shows up mainly in classic and rare vintage coins, not in the modern certified bullion this guide focuses on.
This guide covers how each service started, what actually differs between them, and whether that difference matters when you're buying certified bullion. If you're comparing options, our MS70 1/2 oz Gold American Eagle is available graded by either service.
How Third-Party Grading Actually Works
Before independent grading services existed, a coin's condition was a matter of the seller's own opinion, and the same coin could be described very differently by two different dealers. Third-party grading solved that by having an independent expert assign a numerical grade on the Sheldon scale — a 1-to-70 scale where 70 represents a perfect coin — and then sealing the coin in a tamper-evident holder along with that grade. The holder guarantees that the graded coin and the labeled coin are one and the same, and it protects the coin physically going forward.
PCGS: The Original
According to PCGS's own history page, the Professional Coin Grading Service was formed in 1985 by seven coin dealers and began serving the public on February 3, 1986, making it the first company to combine standardized grading with tamper-evident encapsulation on a large scale. PCGS is headquartered in Santa Ana, California, and pioneered the "slab" format that every major grading service uses today. It's often described as carrying particular weight for classic and rare US coins, where its early reputation was built.
NGC: The Close Second
NGC, the Numismatic Guaranty Company, was founded in 1987, about a year after PCGS, and is now headquartered in Sarasota, Florida. It's the official grading service of the American Numismatic Association and the Professional Numismatists Guild, and it's particularly well regarded for world and ancient coins alongside its US coin work. NGC and PCGS use slightly different terminology for the same concepts — NGC labels early-production coins "Early Releases," where PCGS uses "First Strike," and NGC's "Ultra Cameo" designation for deeply mirrored proofs is the equivalent of PCGS's "Deep Cameo." Our 2026 250th Anniversary Privy Silver Eagle carries NGC's Ultra Cameo label as one example of that terminology in practice.

Choose NGC if:
- You're buying a world, ancient, or non-US coin where NGC has particular strength

Does It Matter for the Certified Bullion We Carry?
For modern certified bullion coins — the MS69/MS70 and PR70/PF70 graded pieces across our American Gold Eagle Coins and similar products — the honest answer is that it rarely matters much. Both services are trusted, both use the same numerical scale, and dealers generally price a top-graded modern bullion coin the same regardless of which service graded it. The premium gap between the two services is a bigger factor for older, rarer coins with genuine collector demand tied to a specific holder, which is closer to what's covered in our explainer on what makes gold proof coins different from bullion.
Frequently asked questions
Is PCGS or NGC the better grading service?
Neither is objectively better. Both are widely trusted, use the same 1-to-70 scale, and are accepted by dealers and collectors worldwide. PCGS has a particularly strong reputation for classic US coins, while NGC is especially well regarded for world and ancient coins.
Do PCGS coins sell for more than NGC coins?
For modern certified bullion, rarely by a meaningful amount. The premium gap between the two services shows up mostly in classic and rare vintage coins with strong collector followings, not in modern MS70 or PF70 bullion pieces.
What does the 1-to-70 grading scale mean?
It's called the Sheldon scale, and it assigns a numerical condition grade to a coin, with 70 representing a perfect coin with no visible flaws even under magnification. Both PCGS and NGC use this same scale, so a 70 from either service represents the same condition standard.
Which grading service is older, PCGS or NGC?
PCGS is older. It was formed in 1985 and began operations in February 1986, about a year before NGC was founded in 1987, making PCGS the first company to combine standardized numerical grading with tamper-evident coin encapsulation.
Can I verify a graded coin's certification number?
Yes. Both PCGS and NGC offer online lookup tools where you can enter a coin's certification number to confirm its grade and details directly from the grading service itself, which is a good way to verify a certified coin before buying.
