Quick answer
Grading adds real value on scarce numismatic coins. On modern bullion, the premium rarely survives resale.
Third-party grading by PCGS or NGC authenticates a coin and certifies its condition on a 70-point scale. For pre-1933 US gold, key-date silver, and expensive classics, that certification justifies a meaningful premium because condition genuinely drives price. For modern bullion like American Gold Eagles or Silver Maples, most coins already grade MS69 or MS70, so the label commands a retail markup that the average coin dealer does not return at buyback. Understanding which category your coin falls into before you pay a grading premium or buy a slabbed modern coin is worth your time.
What PCGS and NGC Actually Certify
Two organizations dominate third-party grading in the United States: the Professional Coin Grading Service (PCGS), founded in 1986, and the Numismatic Guaranty Company (NGC), founded in 1987. Both follow the same basic process: a coin is submitted, examined by multiple graders, assigned a grade, and sealed in a tamper-evident plastic holder often called a “slab.” The slab carries a certification number, the assigned grade, and the coin’s name and date.
Two things the certification gives you: an expert opinion on the coin’s condition, and an authentication that the coin is genuine and not altered. Two things the certification does not give you: a price guarantee, or any promise that a buyer will pay for the grade premium in the future. The grade is a quality assessment, not a valuation.
For buyers of expensive classic coins, independent authentication from a disinterested third party is genuinely valuable. A coin dealer selling you an expensive rarity has an incentive to grade favorably. PCGS and NGC do not.
The Sheldon Scale: What the Numbers Mean
Both PCGS and NGC use the Sheldon scale, a 1-to-70 numerical grading system first described by numismatist Dr. William Sheldon in his 1949 work on early American cents. The scale was adopted industry-wide and now applies to all US and many world coins.
Poor to Good
P-1 to G-6
Heavily worn. Date and type identifiable but detail largely gone.
Very Good to Fine
VG-8 to F-15
Moderate to considerable wear. Main features clear, high points flat.
Very Fine to About Uncirculated
VF-20 to AU-58
Light to slight wear on high points. Still significant numismatic value at top grades.
Mint State
MS-60 to MS-70
No wear. Grades reflect contact marks, luster, and strike quality. MS-70 = perfect.
Proof
PF-60 to PF-70
Specially struck coins with mirror-like fields. Proof-70 = flawless to the naked eye.
For circulated coins with numismatic value, even a one-grade improvement can represent hundreds or thousands of dollars. A 1916-D Mercury Dime graded VG-8 and one graded F-15 are not remotely the same coin in dollar terms. That spread is exactly where third-party grading earns its fee.
The Modern Bullion Math: Why the Label Often Becomes a Tax
Modern bullion coins (American Gold Eagles minted since 1986, Silver American Eagles, Canadian Maple Leafs, and similar government-issued bullion) are manufactured to tight tolerances. The Mint produces them by the millions using modern equipment. The practical result: a very large share of these coins grade MS69 or MS70 when submitted to PCGS or NGC.
PCGS and NGC publish population reports showing how many examples of each coin and date have been graded at each level. For most recent-year American Gold Eagles and Silver Eagles, population reports show tens of thousands of coins graded at the top two levels combined. When that many examples exist at the highest grade, there is no condition scarcity, and condition scarcity is the foundation of numismatic value.
The table below uses illustrative figures to show how the economics typically play out. Verify current dealer spreads using the Goldiew coin dealer directory before making any transaction. Actual premiums and buyback rates vary by dealer, coin, and market conditions.
| Scenario | What you pay (retail) | What most dealers pay back | Who captures the premium |
|---|---|---|---|
| Raw 1 oz Gold Eagle (ungraded) | Spot + small dealer spread | Near spot | Spread goes to dealer |
| Graded MS69 Gold Eagle (slabbed) | Spot + dealer spread + MS69 premium | Near spot (label not valued by most bullion buyers) | Premium stays with original seller |
| Graded MS70 Gold Eagle (slabbed) | Spot + dealer spread + MS70 premium (often 10-20% above raw) | Near spot to slight premium if sold to a numismatic buyer | Premium largely stays with original seller |
The math works against the buyer of modern graded bullion: you pay for a label that most bullion dealers do not price into their buyback. When you later want to sell, you are competing in a secondary market where the slab’s value depends on finding a collector who wants that specific grade designation, not just the metal. If you can find one, you may recover some of the premium. If you sell to a bullion dealer, you likely recover near spot.
Before you pay a grading premium on modern bullion: Check the current population report for the exact coin, date, and variety on PCGS CoinFacts or the NGC Census. If tens of thousands of examples grade MS69-70, the label carries limited numismatic value beyond what a collector niche will pay.
If you are buying gold purely for metal content, raw bullion purchased through a reputable source serves the same financial purpose as a slabbed coin. Our gold value calculator can help you understand what you are paying relative to spot.
Label Marketing Decoded: First Strike, Early Releases, and Similar Designations
Beyond the numeric grade, PCGS and NGC offer special labels for coins that meet certain submission or origin criteria. These labels appear on the slab holder alongside the grade. Understanding what they actually certify (and what they do not) keeps you from paying for marketing.
| Label | Service | What it actually means | What it does NOT mean |
|---|---|---|---|
| First Strike | PCGS | The coin was submitted to PCGS within 30 days of the US Mint’s official release date, as confirmed by documentation | It is not a quality designation. The coin itself is not physically different from a First Strike submitted on day 1 vs a regular submission on day 31. |
| Early Releases | NGC | The coin was submitted to NGC within 30 days of the official release date | Same as above: timing of submission, not coin quality. |
| First Day of Issue | PCGS / NGC | Submitted on the actual release date, with supporting documentation | Still a submission-timing designation. The coin’s strike quality, luster, and surface are identical to any other example of the same type and date. |
| West Point Mint / San Francisco Mint | PCGS / NGC | The coin was struck at that specific Mint facility, confirmed by documentation | For modern bullion, the Mint of origin does not necessarily affect quality. Numismatic significance depends on the specific coin type and date. |
| Burnished / Specimen | PCGS / NGC | Coins struck on specially prepared burnished blanks (Mint designation “W” burnished coins), giving a distinct satin finish | This IS a real production distinction (different from standard bullion strike), but it describes the coin’s origin, not a grade above the numeric rating. |
The key principle: a label describes something about the submission or origin of the coin, while the numeric grade describes its condition. When a modern bullion coin carries both “MS70” and “First Strike,” you are buying the grade, the label, and the slab. The coin’s metal content is the same as any raw example of the same type and date.
PCGS publishes its designation criteria at pcgs.com/grades. NGC publishes theirs at ngccoin.com. Reading the actual definitions takes about five minutes and removes any ambiguity about what a label means.
When Third-Party Grading Genuinely Adds Value
Dismissing all grading would be wrong. For specific coin categories, professional certification is not a marketing expense: it is the difference between buying what you think you are buying and being defrauded, or between realizing full numismatic value and leaving money on the table.
Pre-1933 US Gold
Saint-Gaudens $20 Double Eagles, Liberty Head Eagles, Indian Head pieces: condition drives enormous price gaps. An MS63 Saint-Gaudens Double Eagle can trade at multiples of an AU55 example. Independent grading confirms both authenticity and grade. Counterfeits and cleaned coins exist in this market.
Key-Date and Semi-Key Coins
Coins with low original mintages (1916-D Mercury Dime, 1921 Peace Dollar, 1932-S Washington Quarter, among others) attract fakes specifically because low-population dates command high prices. A certified example from PCGS or NGC gives buyers confidence the coin is genuine and unaltered.
Any Expensive Classic You Plan to Resell
If you are spending $2,000 or more on a single coin, certification protects both your purchase and your eventual sale. A certified coin is easier to sell at a fair price because buyers can verify the grade independently. Uncertified expensive coins sell at discounts to account for the buyer’s uncertainty.
Authentication for Suspected Fakes
If you own inherited coins or pieces purchased without certification and you are unsure of their authenticity, PCGS or NGC submission answers the question definitively. Counterfeit detection is part of the grading service. A coin that fails authentication is returned ungradable.
The unifying factor across all four cases: the coin’s value depends on something beyond its metal content, and an independent opinion on condition and authenticity protects both buyers and sellers.
How to Buy Graded Coins Without Overpaying
If you want to build or buy a collection of genuinely numismatic coins, a few practical tools help you pay a fair price rather than a marketing premium.
Check the population report first. Before you pay a significant premium for any graded coin, look up the population report. PCGS CoinFacts (pcgscoinfacts.com) and the NGC Census (ngccoin.com/census) are free. Find the specific coin, date, and mint mark. Look at how many examples have been graded at that level or higher. If the population is small (dozens or low hundreds at a given grade), condition scarcity may justify a premium. If the population is in the tens of thousands, it does not.
Use price guides as reference points, not gospel. The PCGS Price Guide and NGC Price Guide list estimated values by grade. These reflect what dealers typically ask, not necessarily what recent transactions cleared. For a more accurate picture of what coins actually sell for, check completed auction results on GreatCollections or Heritage Auctions. Hammer prices from real auctions reflect actual market clearing prices, not dealer wishlist pricing.
Verify the certification number. Both PCGS and NGC let you verify any slab by its certification number at their websites. This confirms the coin is genuine and that the slab has not been tampered with. If a seller refuses to let you verify the certification, treat that as a red flag.
Understand the population trajectory. For modern coins still being submitted to grading services, the population at top grades tends to grow over time as more submissions come in. A premium that looks justified by today’s population may compress as that population grows. Older series with a fixed universe of coins are less subject to this dynamic.

A Note on Gold IRA Eligibility
If you are considering a self-directed precious metals IRA, note that the IRS does not evaluate coins on their numismatic grade. Under IRS Publication 590-A and Internal Revenue Code Section 408(m)(3), IRA-eligible gold coins must meet a fineness standard of at least .9950 for gold (with specific statutory exceptions for American Gold Eagles, which are eligible at .9167 fine). Pre-1933 US gold coins are generally NOT eligible for IRAs because they are considered collectibles under IRC Section 408(m)(2).
For modern bullion coins that are IRA-eligible, most IRA custodians prefer or require raw bullion rather than graded slabs, partly for administrative simplicity and partly because the slab itself does not change the coin’s eligibility or metal content. Consult your IRA custodian and tax advisor for your specific situation before including any coin in a retirement account.

Frequently Asked Questions
Does grading increase the resale value of my American Gold Eagle?
For most modern American Gold Eagles, grading adds a retail premium that many bullion dealers do not price into their buyback offers. If you sell to a bullion buyer, you will likely recover near spot price regardless of whether your coin is graded. If you sell to a numismatic collector who specifically wants a high-grade certified example, you may recover some or all of the premium. The key variable is your buyer: bullion buyers price metal content, numismatic buyers price condition and certification.
What is the difference between First Strike and Early Releases?
Both designations indicate that the coin was submitted to the grading service within 30 days of the US Mint’s official release date. “First Strike” is the PCGS term; “Early Releases” is the NGC equivalent. Neither term describes the physical quality of the coin itself. A coin graded MS70 First Strike and one graded MS70 with no special designation are the same grade and the same coin quality. The designation reflects submission timing, not the coin’s condition.
Are graded coins still IRA-eligible?
IRA eligibility under IRC Section 408(m)(3) is determined by the coin’s type and fineness, not its grading status. Modern American Gold Eagles are IRA-eligible whether raw or slabbed. However, most IRA custodians prefer or require raw bullion for administrative reasons, so confirm with your custodian before submitting a slabbed coin to an IRA. Pre-1933 US gold coins (which are the most common reason to grade a coin for numismatic value) are generally not IRA-eligible because they fall under the collectibles prohibition in IRC Section 408(m)(2). Consult your tax advisor for your specific situation.
How much does PCGS or NGC grading cost?
Both PCGS and NGC offer tiered grading fees based on the declared value of the coin and the requested turnaround time. Economy/value tiers with longer turnaround are the least expensive; express and premium tiers with faster returns cost more. Specific fee schedules change periodically, so check the current rates directly at pcgs.com/services or ngccoin.com/submit. The grading fee is a cost you incur before you know the assigned grade, so it makes most sense for coins where the expected numismatic premium at the anticipated grade exceeds the submission cost.
What is a population report and why does it matter for pricing?
A population report (or “pop report”) shows how many examples of a specific coin, date, and mint mark have been graded at each grade level by PCGS or NGC. A low population at a given grade indicates condition scarcity, which supports numismatic value. A high population at a grade (particularly for modern coins) indicates that condition scarcity does not exist at that level, which limits the numismatic premium regardless of what retail asking prices suggest. PCGS CoinFacts and the NGC Census both publish population data for free.
Should I submit my coins to PCGS or NGC before selling?
Submission makes sense when the expected premium from certification, net of grading fees and turnaround time, exceeds what you can recover by selling raw. For pre-1933 numismatic coins where condition drives price and buyers expect certified examples, submission typically makes sense. For modern bullion coins, the math usually does not work: most coins will grade MS69-70 (no surprise to sophisticated buyers), grading fees add to your cost basis, and most bullion buyers price metal rather than grade. Posting a free request on Goldiew’s sell-gold page to get offers on your raw coins before deciding to grade is a low-cost way to understand the market.
What makes a pre-1933 US gold coin worth grading before selling?
Pre-1933 US gold coins (Saint-Gaudens $20 Double Eagles, Liberty Head Eagles, Indian Head coins) have fixed populations: no more will ever be minted. Condition therefore drives real scarcity. The price gap between grades can be substantial: the difference between an AU55 and MS63 example of a common date Saint-Gaudens can represent thousands of dollars. Buyers of these coins expect certified examples from PCGS or NGC for any serious transaction. Certification also rules out cleaned, improperly repaired, or counterfeit coins, which do exist in this market. For uncertified examples at the upper end of circulated or lower mint-state grades, PCGS or NGC submission before sale often pays for itself.
