Learn About the Factors That Determine Numismatic Value
The numismatic value of a coin depends on three factors: the date and mintmark of the coin, the mintage/population of the coin and its condition or finish. A seemingly small or insignificant flaw can go a long way in affecting a coin’s value. The best way to validate the quality of Precious Metal coins is to assign a grade to the coin. Through obtaining knowledge about grading, one can accurately define the grade of the coin.
If one is not comfortable in their grading skills, there are two important considerations:
- Know the coin dealer from whom you have purchased the coin. A reliable dealer will stand behind what they sell and they will accurately grade their coins.
- Buy certified coins that have been graded through an independent and reliable third party.
Any reputable dealer who sells you coins will determine the grade of the coin and, therefore, its value through coin grading. This process not only helps determine the numerical grade of the coin but also determines the value of the coin. The grading process, however, is subjective because there are various elements to coin grading that are valued differently from person to person.
There are several qualities a coin is graded on. A coin’s strike is how fully the details of the coin are struck on the surface, while luster determines how the coin reflects light back into your eyes. Additionally, eye-appeal is how attractive one considers a coin in their personal opinion. These aesthetic factors are all subjective to the personal likes and dislikes of the viewer.
Professional Coin Grading Service
In the United States, grading companies are ranked into three main tiers based on their reputation for consistent and reliable evaluations and acceptance in the numismatic marketplace. Certified coins by the two top-tiered grading services command the highest premiums in the numismatic marketplace.
The Professional Coin Grading Services (PCGS) and the Numismatic Guaranty Corporation (NGC) are rated as “Superior” by the Professional Numismatists Guild. Coins graded by PCGS or NGC have high-grade authenticity and are accepted in the marketplace at their stated grade.
The middle-tiered grading service ANACS has been in existence the longest, but their grading is acceptable. ANACS graded coins generally trade at lower premiums than PCGS or NGC graded coins. All the other companies not mentioned above are considered the lowest tier of grading services. Coins graded by any other company will likely be devalued because of inconsistent or “looser” grading standards.
When choosing a grading service, it’s best to choose one of the two top-tiered companies PCGS or NGC.
Why is Coin Grading important?
The grade is how numismatists determine the coin’s “state of preservation”. Grading has been relevant in the United States since coins were starting to be collected in the mid-19th Century.
Coin grades have four categories. They are Poor, or well-worn with outlines but no details; Good, meaning that there is much wear, but details are present; Very Fine, contains many details but has some wear; and New, or it shows no wear and all details present. Prices do not vary significantly between grades.
Coin grading remained relatively unchanged for 100 years. In 1949, Dr. William Sheldon decided that there were many additional “states of preservation” of coins. Sheldon developed a system of grading coins on a scale from 1 to 70, with “1” representing a Poor coin lacking virtually all details to “70” representing a “Perfect” coin.
The upper portion of the Sheldon scale is for Uncirculated coins grading from 60 to 70. These Uncirculated coins have no wear and are graded based on the severity, number, and location of marks and imperfections. Dr. Sheldon used these 13 “grades” to represent the 1 to 70 scale:
- Almost Good
- Very Good
- Very Fine
- Extra Fine
- Almost Uncirculated
- Brilliant Uncirculated
- Gem Uncirculated
- Perfect Uncirculated
This served the numismatic community well for 30 years. In the mid-1980s a group of coin dealers decided to form an independent third-party coin certification service. The main idea was to standardize grading among dealers and to bring consensus grading to the marketplace.
Grading Coin Services
When a dealer submits a coin to a grading service, it is graded by at least two experts. The two experts must independently agree on the coin’s condition. If they disagree, a third expert, a finalizer, will review it.
After grading, a coin is “slabbed” (encapsulated in tamper-resistant plastic with the coin’s consensus grade printed on a tag inside the slab). Companies use encapsulating technology for the long-term storage and protection of coins.
Do All Coins Require Grading or Coin Certification?
The answer is: no. Not all coin purchasers need certification and not all coins are worth the time and expense that certification may add to the cost of the coin. If you are a seasoned coin purchaser, you have seen many coins and you can compare any coin offering to other coins within your collection. Further, if the cost of the coin is modest then the cost for this additional certification may be unnecessary and undesirable.
Costs for certification may run from $15 to more than $100 per coin, depending on the coin’s value and the time frame the dealer wants it returned to them. Coins of modest value may not demand certification. Those wanting to buy Gold and other Precious Metals to add to their collection may be better off not grading certain coins if grading. As an experienced purchaser, you are likely to collect these items and place them in albums with other similarly graded coins.
Graded Coin Certification
Again, coin certification is likely not desirable in that instance. If you cannot locate a professional and reliable coin dealer, then coin certification may be desirable. If you cannot find a dealer who will stand behind what they sell, coin certification may be desirable. As the buyer, you need to determine if the additional expense is justified and if you are comfortable with the additional expense.
Even if you are a seasoned collector, certification is certainly advisable for expensive acquisitions. That decision is, ultimately, up to the buyer.
Certified coins must be certified by NGC, PCGS, ICG or ANACS to be Sold on eBay
PCGS and NGC both maintain an online census or population report of coins they have graded. These reports help determine whether a coin is rare or common in certified grades. Through NGC certification or PCGS certification, coins receive a unique serial number for identification purposes.
PCGS and NGC coin grades can also be further qualified with additional scrutiny from the Certified Acceptance Corporation (CAC). CAC reviews only NGC or PCGS graded coins and, if they agree with the grade, affix a small sticker to the slab to attest to their acceptance of the grade. This is done, as you might imagine, for an additional fee.

Is Buying a Graded or Certified Coin Worth It?
Professional coin grading services are fee-based. Fees depend on several factors such as the declared value of the coin, its condition, and the requested turnaround time. However, once coins receive coin grades and are certified by a respected coin grading company, their numismatic value may be enhanced by the company’s reputation and grading guarantee.
Trusted seals of authenticity and condition may make coins worth more overall. But as the potential buyer, you should discuss these options with your trusted coin dealer to determine whether these additional expenses are justified and financially warranted.
