PCGS and NGC are the two largest independent third-party coin grading services in the United States. Both authenticate a coin, seal it in a tamper-evident holder with a certification number, and assign a grade on the 1-to-70 Sheldon scale. Neither is universally “better”: collectors and investors compare the specific coin, its grade and its price, and the market treats top grades from both services as fully credible.
This guide compares the two services on what actually matters when you buy: the grading scale, the holder, the population reports, and how each name affects price. New to grading? Start with our coin grading guide, then come back here for the head-to-head.
Coin grading is the professional assessment of a coin’s authenticity and condition. Independent services grade on the 1–70 Sheldon scale: 1 is a barely identifiable piece of metal, 58 shows a trace of friction on an otherwise unworn coin, and 70 is perfect as struck, with no post-production imperfections visible at 5× magnification. Because the graded coin is sealed in a holder with its certification number, anyone can verify the grade free online — the grade travels with the coin, not with the seller’s word. That is what makes graded (“slabbed”) coins liquid.
Both services grade on the same 1–70 Sheldon scale, using MS for mint state, PF for proof, and SP for specimen strikes. Coins with post-mint problems are encapsulated with a “genuine” or “details” notation instead of a numeric grade. The real differences are below.

| Market premium | Top grades widely accepted at major auctions; premiums vary by series, date and grade (check the PCGS Price Guide) | Top grades widely accepted at major auctions; premiums vary by series, date and grade (check the NGC Price Guide) |
Neither holder earns a blanket premium. The market pays for the specific coin — date, grade, eye appeal and certification — so check recent auction results for your exact coin before paying extra for either name.
Both services accept submissions from collectors; you do not have to be a dealer. The workflow is the same at each: pick a submission tier based on your coin’s declared value and turnaround, pay the tier fee, ship the coins insured to the grading facility, and receive them back sealed in holders with certification numbers. Fees, membership requirements and turnaround times change regularly — check the current submission pages at PCGS and NGC before sending anything.
If you are buying rather than submitting, the shortcut is to buy coins that are already graded — see our certified gold coins and certified silver coins.
Buying a graded coin is mostly a verification exercise. Every PCGS and NGC holder carries a certification number, and both services publish free online lookup tools: PCGS Cert Verification at pcgs.com/cert and NGC Cert Lookup at ngccoin.com/certlookup. Enter the number and confirm that the coin description, grade and any label match the holder in front of you. If a seller will not provide the certification number before payment, treat that as a reason to walk away.
Ask the dealer five questions before you buy:
Verify the certification number yourself on the service’s site before money changes hands, and price the exact date, grade and designation against recent auction results for comparable coins. The grading service’s name alone is rarely worth a blanket premium.
You can browse our graded gold coins and graded silver coins to see the grading service and grade listed for every coin, then verify the certification number on the service’s site before you buy.
Labels add context the numeric grade does not capture. Two you will see most often:
First Day of Issue is an NGC designation. To qualify, the coin must be purchased within one day of the date the mint first makes it available, and NGC or an NGC-approved depository must receive it within one week of release. It records when the coin was bought and submitted, not its condition, so an FDOI coin can carry any numeric grade. PCGS’s related designation is First Strike, which covers coins shipped from the mint within a set early window (30 days for most releases). It is also not the same thing as a philatelic “first day cover,” which is a stamped envelope rather than a coin.
Ultra Cameo is NGC’s strongest contrast designation for proof coins: frosted devices raised sharply against deep, mirror-like fields. PCGS’s equivalent term is Deep Cameo (DCAM), and the weaker contrast level is simply Cameo on both services. The designation sits alongside the numeric grade, so a label can read PF70 Ultra Cameo, a perfect proof grade with the top contrast level. For an example of how grade and label appear together on a listing, see this NGC PF70 Silver Eagle.
Compare the coin, not the logo: date, grade, eye appeal, certification number and price. Both services’ top grades are accepted everywhere serious coins trade, and both are represented in our inventory — for example, the 2025 $100 Gold Liberty PCGS PR70 signed by David Hall and the 1986 $50 Gold Eagle NGC MS70 signed by Miles Standish. Collectors who build registries or chase population-report rarities will care which holder they buy; everyone else can simply buy the better coin at the better price.

Neither is universally better. Both are top-tier, and the market pays for the specific coin. Compare date, grade, eye appeal and price, and verify any certification number free online before you buy.
