Ancient Coin Grading
NGC Explained Simply
Ancient coins were hand-struck, used in daily life, buried for centuries, and later recovered. No two examples are ever truly identical and grading reflects that reality.
The Basics
What grading means
for ancient coins Unlike modern coins, ancient coins were handmade. Grading describes preservation but that is only part of the story. NGC Ancients uses a descriptive system instead of the modern 1-70 numerical scale.

MSMint StateNo circulation wear
AUAbout UncirculatedTrace wear only
XFExtremely FineLight wear
VFVery FineModerate wear, clear devices
FFineConsiderable wear
VGVery GoodHeavy wear, main features visible
GGoodVery heavy wear
Key insight: Weak details caused by worn dies or a soft strike do not count as wear. A coin can appear soft without being worn.
The NGC System
Four things NGC
evaluates on every coin NGC does not judge ancient coins by a single number alone. Every coin is assessed across four separate components, each telling a different part of the coin's story.
evaluates on every coin NGC does not judge ancient coins by a single number alone. Every coin is assessed across four separate components, each telling a different part of the coin's story.
Component 01
Grade
Measures circulation wear
How much detail has been lost from use in antiquity. This is the only component that reflects actual wear.
From Fair (heavy wear) to Mint State (no wear)
Weak strike is never confused with wear
Component 02
Strike
1 to 5 scale
How well the coin was made at the moment it was struck. A coin can have a high grade but a low strike.
Centering of the design
Strength and evenness of the strike
Die wear, cracks, or planchet flaws
Overstriking or double strikes
Component 03
Surface
1 to 5 scale
Everything that happened after the coin was struck, excluding wear. Ancient coins were buried for centuries.
Cleaning, smoothing, or scratches
Porosity, corrosion, or encrustation
Patina quality, especially on bronze
Burial and recovery effects
Component 04
Style
Fine Style designation
Ancient dies were hand-engraved. Coins with superior engraving may receive a Fine Style designation.
Quality of engraving and composition
Compared to coins from the same series
Not every coin from a fine-style die qualifies
Why this matters: A coin can grade higher than it looks because softness from worn dies is reflected in the Strike score, not the Grade.

What is a Net Grade?
A Net Grade is a single overall grade accounting for all strengths and weaknesses together. It reflects how a coin trades in the marketplace as a whole.
Lightly worn coin plus rough surfaces may net to VF
Sharp strike plus poor surfaces may also net to VF
How to read any ancient coin
Together, all four components tell the full story of what a coin is and how it got there.

Final Thought
Ancient coins are not products.
They are survivors of history. Grading exists to explain their condition, not to demand perfection. Understanding how grading works allows collectors to buy with confidence and appreciate what makes each piece truly unique.
