Coin Grading Guide

Grade is the single biggest factor in Roman coin pricing. An Augustus denarius in EF can sell for three to five times the same type in F. Understanding grades helps you assess whether a coin is good value before you buy.

The Grading Scale

MS

Mint State

Uncirculated. No wear whatsoever.

Example coin image — MS

Exactly as struck — every detail razor-sharp, original mint lustre preserved. Exceptionally rare for ancient coins, which spent centuries underground.

AU

About Uncirculated

Slight traces of wear on the highest points only.

Example coin image — AU

Just a whisper of circulation. High relief areas (portraits, eagle wings) may show faint friction. Most of the original lustre survives.

EF

Extremely Fine

Light even wear on highest points. Sharp overall.

Example coin image — EF

The practical top grade for most collectors. All design elements clear and well-defined. Hair strands, legend letters, and reverse details all legible.

VF

Very Fine

Moderate wear on high points. All major features sharp.

Example coin image — VF

The most common collector grade. Portrait still strong, major details present, though fine hair and drapery lines may be softened by wear.

F

Fine

Even moderate to considerable wear. All design elements visible.

Example coin image — F

Portrait and reverse recognisable but smoothed. Legend fully readable. A good entry point for rare types where better grades are unaffordable.

VG

Very Good

Well worn. Design clearly visible but flat.

Example coin image — VG

Main design outline clear, but surface detail largely worn away. Legend may be partially worn but still readable.

G

Good

Heavily worn. Design visible but faint in spots.

Example coin image — G

The portrait outline survives but features are mostly flat. Legend may be incomplete. Chosen only for very rare types.

AG

About Good

Extremely worn. Portions of legend visible.

Example coin image — AG

Barely identifiable. Typically purchased only for historical interest or as a placeholder for an impossibly rare type.
