The Complete Guide to
Coin Grading Services

PCGS, NGC, and everything in between. Learn what grading means, why it matters, and how the major services compare — so you can buy and sell with confidence.

Why It Matters

Grading transforms a coin into a verified asset

A raw (ungraded) coin is worth whatever someone thinks it's worth. A graded coin has a certified condition, authenticated provenance, and a market price. The difference is often 2–10× in value.

🔒

Authentication

Third-party graders verify the coin is genuine — not a replica, cleaned, or altered. This eliminates counterfeiting risk for buyers.

📊

Standardized Grading

The 70-point Sheldon scale gives every coin a precise condition score. MS-65 means the same thing regardless of who you're buying from.

💰

Proven Value

Certified coins consistently sell for more. Population reports show how rare a specific grade is — scarcity drives premium pricing.

🏦

Tamper-Evident Holder

Coins are sealed in a hard plastic "slab" with a label showing grade, date, and mint mark. Tampering destroys the holder visibly.

📈

Market Liquidity

Certified coins trade faster because buyers trust the condition. PCGS/NGC-graded coins are the universal currency of the hobby.

🌐

Online Verification

Every slab has a certification number you can verify in real-time at the grader's website. Buyers confirm authenticity before purchase.

The Sheldon Scale

From Poor-1 to Mint State 70

Developed by Dr. William Sheldon in 1948, the 70-point scale is the universal language of coin grading. Both PCGS and NGC use it. Here are the key grades and what they mean for value.

PO-1
Poor
Barely identifiable. Date/type readable.
G-4/6
Good
Heavily worn. Major design visible, flat detail.
VG-8/10
Very Good
Well worn. Main features clear, some detail.
F-12/15
Fine
Moderate wear. All major features sharp.
VF-20/35
Very Fine
Light-moderate wear on high points.
EF-40/45
Extremely Fine
Light wear on high points only. Attractive.
AU-50/58
About Uncirculated
Traces of wear, most luster present.
MS-60/70
Mint State
No wear. Ranges from baggy (60) to perfect (70).
MS-65
Gem Uncirculated
Strong luster, minor contact marks. Sweet spot for value/price.
MS-70
Perfect Uncirculated
Flawless under 5× magnification. Extremely rare. Maximum value.
PR/PF
Proof
Specially struck collector coins with mirror-like fields.
PL/DPL
Prooflike
Business strike with proof-like reflective fields.

Why grade points matter for price: A 1881-S Morgan Dollar in MS-64 trades around $150. In MS-65, it's $200. In MS-66, it can reach $1,500+. One grade point at the top of the scale can mean 10× the value. This is why professional grading — not guessing — is essential for serious collectors and sellers.
