Coin Grading Basics:
What Does MS65 Mean and Why Does It Matter?

If you've inherited a coin collection or are sorting through old coins, you've probably seen grades like "MS65," "VF30," or "PR70" on holders or in price guides. These aren't arbitrary labels — they're standardized numeric grades that can mean the difference between a coin worth $50 and one worth $5,000. Here's what they mean and why they matter when you're selling.

The Sheldon Scale: 1 to 70

Coin grades in the U.S. use the Sheldon scale, developed by Dr. William Sheldon in 1949. The scale runs from 1 (barely identifiable) to 70 (theoretically perfect). It has two main categories:

• Circulated grades (1–59): Coins that have been used as money and show wear
• Mint state grades (MS-60 through MS-70): Coins that have never been in circulation

There's also a separate designation for proof coins (PR or PF), which are specially struck with polished dies for collectors.

Circulated Grades Explained

Grade	Name	Description
AG-3	About Good	Heavily worn, design barely visible
G-4/6	Good	Heavily worn, design clear but flat
VG-8/10	Very Good	Moderate wear, main features clear
F-12/15	Fine	Even moderate wear on high points
VF-20/30/35	Very Fine	Light to moderate wear, details clear
EF/XF-40/45	Extremely Fine	Slight wear on high points only
AU-50/55/58	About Uncirculated	Trace wear only on highest points, most luster present

Mint State Grades: MS-60 through MS-70

Mint state coins show no wear — but that doesn't mean they're all equal. The MS-60 to MS-70 range grades surface quality: bag marks (contact marks from other coins), luster, eye appeal, and strike sharpness.

• MS-60 to MS-62: Uncirculated but heavily marked, dull luster, poor eye appeal. Often not worth much more than face value or silver/gold content.
• MS-63: Choice uncirculated. Noticeable marks but overall attractive. Commonly seen in collector markets.
• MS-64: Choice uncirculated, better. Minor marks, good luster. Significant collector premium for key dates.
• MS-65: Gem uncirculated. Only light scattered marks, above-average strike and luster. This is where serious collector premiums begin for most series.
• MS-66 and above: Premium gem. Increasingly difficult to find. MS-67 and above can be worth 10–100× an MS-65 coin of the same date.
• MS-70: Theoretically perfect. Essentially impossible for most coins; modern bullion coins occasionally achieve this.

Why MS65 vs. MS64 Can Mean Thousands of Dollars

For common-date coins, grade differences are modest. But for key dates in popular series, a single grade point can mean enormous value differences. Examples:

• 1881-S Morgan Dollar: MS-64 ≈ $150, MS-65 ≈ $400, MS-66 ≈ $1,800
• 1928 Peace Dollar: MS-63 ≈ $600, MS-65 ≈ $5,000+
• 1922 Plain (no-D) Lincoln cent: VF-20 ≈ $500, EF-40 ≈ $1,500

This is why professional grading matters for potentially valuable coins.

PCGS and NGC: The Two Major Grading Services

Professional Coin Grading Service (PCGS) and Numismatic Guaranty Corporation (NGC) are the industry standard third-party grading services. When a coin is graded by PCGS or NGC, it's placed in a sealed plastic holder (a "slab") with the grade printed on it.

Slabbed coins from PCGS or NGC sell at premiums over raw (ungraded) coins of the same grade because the grade is guaranteed by a reputable third party. If you have slabbed coins, check the PCGS or NGC website for current population reports and price guides.

Getting coins graded: Costs $30–$100+ per coin depending on service level. Only worthwhile if the graded value will exceed the cost — typically makes sense for coins that appear to be MS-63+ or for key dates in any grade.

What This Means When Selling

For most common coins in circulated grades, grade affects value modestly — they're priced primarily by silver or gold content. Where grading really matters:

• Key date coins in any series (1916-D Mercury Dime, 1909-S VDB Lincoln cent, 1893-S Morgan Dollar)
• Mint state coins that appear to be MS-63 or better
• Any coin where you're unsure if it has collector value beyond melt

Before selling, look up your coins in the Red Book (A Guide Book of United States Coins, updated annually) or on PCGS CoinFacts. If a coin might be worth significantly more than melt in high grade, have it graded first.

FAQ

Should I clean my coins before selling?

Absolutely not. Cleaning a coin — even gently — destroys its surface and eliminates any numismatic premium. A cleaned MS-65 becomes a problem coin worth far less. Never clean coins before having them evaluated.

What if my coin isn't graded by PCGS or NGC?

Most coins aren't slabbed — that's normal. Raw coins are evaluated by knowledgeable buyers on their apparent grade. The risk with raw coins is that you're relying on the buyer's grading, which is why having the Red Book handy and knowing what your key dates are worth matters.

I have a proof set from the 1960s. Is it valuable?

Most 1960s proof sets are worth their silver content (pre-1965) or a small premium over face value (1965+). They're common. The key is whether any individual coin in the set is a major variety or error. Look at each coin carefully, or bring the set in for evaluation.
