Grading coins accurately is one of the most
valuable skills a numismatist can learn. What exactly is meant by
grading coins, and why is this important?
Developing a working knowledge of the art of
coin grading is one of the
first and most important steps in becoming a successful numismatist.
|Intro to Grading Coins|
The science of grading coins is not the same as
the science of physics
or mathematics, where formulas yield an answer “Z”, given inputs “X”
and “Y”. No, grading coins with great precision is a talent, resulting
from the nexus of knowledge, experience, and practice.
Fortunately, the novice coin collector need not
be intimidated by the subjectivity aspect of grading coins. Any person,
even a newcomer, can develop enough skill and confidence to approximate
the condition of nearly any coin, through diligent reading and studying
as many coins as possible, whose conditions are already known.
The first step in gaining a clearer understanding of how to grade coins
is to acquire the “bible” of grading coins, the Official
ANA Grading Standards for United States Coins. Written by longtime veteran
numismatist Kenneth Bressett and produced by the American Numismatic
Association, this valuable reference is the foundation upon which all
other coin grading books are written, and deserves a place in the
personal libraries of all coin collectors. We strongly recommend it,
especially for people wanting to learn the basics. Full Review here.
An important sidekick publication, Photograde, is also recommended.
Designed for beginners and advanced coin collectors alike, every
regular issue United States coin type from 1793 to date is illustrated,
many of them enlarged to show greater detail. For an detailed look at
what Photograde has to offer, we have an
online review (18th ed.).
Another top-of-the-line coin grading book worth
recommending is The
Official Guide to Coin Grading and Counterfeit Detection
Official Guide to Coin Grading and Counterfeit Detection, Edition #2. The book was produced by the
grading experts at Professional Coin Grading Service, better known as PCGS, and edited by coin collector "Superman", Scott
Travers. PCGS is one of the oldest third party coin certification
companies, beginning operations in the 1980's. It is regarded by
most collectors and dealers alike as one of the best grading services
|Historical Overview on US Coin Grading|
Going back to the 1950s and before, coin grading
was limited to a few adjectival terms, such as Good, Fine,
Uncirculated, and Proof. Accordingly, numismatic references of those
times conformed to the same set of adjectives to approximate retail
Varying distinctions of Uncirculated (today's
equivalent of MS-60,
MS-63, etc.) and Proof were recognized in some advertisements and
auction bills by employing modifying descriptors such as "Gem
Uncirculated" or "Choice Proof", for example. However, with no clear
point of reference or consistency on how the modifying descriptors were
invoked, most publishers resorted to listing values for only one
"Uncirculated" grade and one "Proof" grade.
|The 70 Point Coin Grade Scale|
The process of coin grading is highly subjective. Even though talent and experience is the key to grading coins accurately on a consistent basis, beginners can come reasonably close to approximating grades with a few simple guidelines. The American Numismatic Association's 1-70 point numeric system is frequently invoked to assign coin grade. The following grades and descriptions are the most recognized milestones on the typical coin grading continuum.
|About Good||AG-3||Very heavily worn with portions of the lettering, date, and legends being worn smooth. The date is barely readable.|
|Good||G-4||Heavily worn. Major designs visible, but with faintness in areas. Head of Liberty, wreath, or other major features visible in outline form without center detail.|
|Very Good||VG-8||Well worn. Most fine details such as hair strands, leaf details, and so on are worn nearly smooth. The word LIBERTY, if on a shield or headband (seen on 28 coin types), is only partially visible.|
|Fine||F-12||Moderate to considerable, even wear. Entire design is bold. All lettering, including the word LIBERTY is visible, with some weaknesses.|
|Very Fine||VF-20||Same as Fine except with only moderate wear on the highest points.|
|Choice Very Fine||VF-30||Has light even wear on the surfaces, design details on the highest points are lightly worn, but with all lettering and major features sharp.|
|Extremely Fine||XF-40 or
|Design is lightly worn throughout, but overall, features are sharp and well defined. A bit of luster may show.|
|About Uncirculated||AU-50||Has a trace of wear on many of the highest areas. At least half the original mint luster is still present.|
|Choice About Uncirculated||AU-55||A coin having less than a trace of wear on only the highest points of the design but no other defects and with most of its luster remaining.|
|Mint State||MS||The term (MS) can be interchanged with Uncirculated (UNC) to describe "new" coins showing no trace of wear. There are 11 grades of MS coins, ranging from MS-60 to MS-70.|
|Uncirculated||MS-60||Has no trace of wear but may show a large number of detracting contact marks and scuffs. Surface may be spotted or lack some luster. Lots of hairlines and rim nicks are permissible. Poor eye appeal is typical.|
|Uncirculated||MS-61||Reduced mint luster, contact marks and scuffs scattered throughout. Hairlines may be very noticeable. Small rim nicks are OK. Eye appeal is somewhat unattractive.|
|Uncirculated||MS-62||Reduced mint luster may be evident. Groups of small marks throughout, with a few large marks or scuffs highly visible. Scattered hairlines. Rim quality and overall eye appeal below average.|
|Uncirculated||MS-63||May have slightly impaired luster. Noticeably fewer defects throughout. A small number of heavy marks are acceptable. Somewhat attractive eye appeal.|
|Uncirculated||MS-64||Average mint luster. Several small contact marks in groups and a couple of moderately heavier marks are OK. One or two small hairline patches. Overall eye appeal is good.|
|Uncirculated||MS-65||Above average mint luster. Only a few scattered contact marks or two larger marks are present. One or two hairline patches. A few light scuffs on highest points of coin. Quality and eye appeal are above average and quite pleasing.|
|Uncirculated||MS-66||Above average mint luster. No more than a few minor contact marks; some in prime focal areas OK. A few hairlines or light scuffs show under magnification. Eye appeal is very good.|
|Uncirculated||MS-67||Has almost all of original mint luster. No more than three or four very small contact marks. One or two small hairlines or scuffs acceptable. No distracting flaws allowed. Exceptional eye appeal.|
|Uncirculated||MS-68||Full original mint luster. No more than four scattered very small contact marks or flaws, none in focal areas. No visible hairlines or scuff marks. Exceptional eye appeal.|
|Uncirculated||MS-69||Very attractive, full mint luster and sharp strike. No more than two small non-detracting marks or flaws. No visible hairlines or scuff marks. Exceptional eye appeal.|
|Uncirculated||MS-70||Full original luster of the highest quality. No flaws whatsoever visible, even under 4x magnification. Outstanding eye appeal. The perfect coin.|
|A specially made coin distinguished by sharpness of detail and usually with brilliant mirror-like surfaces. Proof refers to the method of manufacture and is not a condition. There are 11 grades of PR coins, ranging from PR-60 to PR-70.|
|Proof||PR-60||Unattractive with little if any mirror characteristics. May be large detracting contact marks or damage spots. Heavy hairlines and possible large scuff marks. Rim nicks and poor eye appeal.|
|Proof||PR-61||Mirror characteristics diminished or greatly impaired. Large and small contact marks throughout. Lots of detracting hairlines. Unattractive eye appeal.|
|Proof||PR-62||Original or impaired mirror characteristics. May have distracting marks in prime focal areas. Hairlines throughout. Marginally acceptable eye appeal.|
|Proof||PR-63||Mirror field may be slightly impaired. Numerous small contact marks and a few heavy marks are expected. Many light hairlines are visible without magnification. Moderate eye appeal.|
|Proof||PR-64||Fully original mirror fields. May have a fair number of small contact marks, but only one or two heavier marks are acceptable. A few hairlines under low magnification are OK. Pleasing eye appeal.|
|Proof||PR-65||High quality mirror surface. A few small scattered contact marked, or two larger marks, are OK. A few hairlines under magnification are visible. Very pleasing eye appeal.|
|Proof||PR-66||Full mirror surface and above average quality strike. No more than two or three minor but noticeable contact marks. A few light hairlines may show under magnification. Above average eye appeal.|
|Proof||PR-67||Full mirror surface and sharp strike. Three or four tiny contact marks, with one or two in prime focal areas. No hairlines visible to the naked eye. Exceptional eye appeal.|
|Proof||PR-68||Full mirror surface and attractive sharp strike. No more than four light scattered flaws. No hairlines. Exceptional eye appeal.|
|Proof||PR-69||Full mirror surface and very attractive sharp strike. One or two very small flaws, none in in prime focal areas. Exceptional eye appeal.|
|Proof||PR-70||Full mirror surface and highest quality strike. No flaws visible, even under magnification. Outstanding eye appeal. The perfect coin.|
|Modifying Factors||After evaluating for wear, other indicators, even more subjective, also contribute towards the coin’s overall grade. These "Modifying Factors", some of which are mentioned above, include eye appeal, quality (i.e. strength) of strike, and blemish location. Other modifying factors are natural toning and coloration. You can learn about them and more in the Coin Jargon glossary.|
|Coin Grading Companies Change the Hobby|
Complaints over inconsistent grading practices
reached a crescendo by the mid 1980s. While one dealer might assign a
coin a certain grade, another dealer might give the same coin a
slightly higher or lower grade. In the numismatic profession,
subtle grade differences can mean literally thousands of dollars in
trading value. In 1986, PCGS began
offering third party grading services, for a fee, to be joined the
following year by NGC.
submitted to these coin grading companies were evaluated by a panel of
experts. Each coin was then encapsulated in a tamper evident
container and returned to the sender. By the late 1980s, the coin
grading companies captured the trust of the coin industry, at last
providing some much desired consistency in grading coins.
|Who are the Coin Grading Companies Today?|
