What does a coin grade tell you?

A grade is a concise description of a coin's condition. Learn what specialists look at, how common terms compare, and where a number can leave questions unanswered.

Beyond a number

How condition is assessed

A sound assessment looks at the whole coin. Lighting, magnification and the coin series all matter.

01

Wear

Circulation can flatten raised details. Wear is judged on the design and series, not age alone.

02

Strike

Some details may be weak from the original minting. A soft strike is not automatically circulation wear.

03

Surfaces

Marks, scratches, cleaning, corrosion, repairs and handling can change a coin's condition.

04

Lustre & eye appeal

Original mint lustre, colour and overall visual balance help complete the assessment.

The Sheldon numeric scale

The slider is an illustration, not a grading tool. Every coin is judged individually, and grading-service terms can vary.

Condition example

A certified grade describes the coin examined, not every coin of the same date and type.

A higher number is not a price estimate. Rarity, demand, authenticity and market conditions also affect value.

Common British descriptions

Fine, VF, EF and UNC

These broad terms describe preservation. The exact boundary depends on the coin, series and standard being used.

F

Fine

Clear circulation wear; the main design remains identifiable.

VF

Very Fine

Moderate wear, with more of the smaller design details still visible.

EF

Extremely Fine

Light wear, often on the highest points; most detail remains sharp.

UNC

Uncirculated

No circulation wear, though marks, toning or a weak strike may still be present.

Independent certification

Authentication and grading are related, but not identical.

Third-party services may assess authenticity and condition, assign a grade, then seal accepted coins in a labelled holder. The holder helps protect the coin and carries its certification details.

A certificate records the service's opinion at the time of grading. It does not make a coin flawless or guarantee a future selling price. Check the named service and certificate record when one is provided.
