When appraising currency collectors and dealers rely on a widely accepted rating system that ranges from Poor to Mint State. This scale defines the level of preservation and, by extension, its market price. The journey from Poor to Mint State illustrates its resistance to degradation and its resilience against daily use and atmospheric damage.

The starting point on the scale is Poor. A coin in Poor condition is extremely degraded, often to the point where details are barely recognizable. The date and design elements may be nearly illegible or smoothed flat, and the coin might show signs of visible blemishes including scuffs, dents, and oxidation. Despite its poor appearance, even a coin in this state can hold value if it is rare or historically significant.

Above Poor is Fair, where the coin is marginally improved from Poor but still heavily worn. Some details may be partially legible, but the overall design is mostly blurred. The coin may still have noticeable flaws, and its surface might be uneven or discolored.

Coins graded Good display increased clarity. Major design elements are well-defined, though minor details are eroded. The coin’s rim is usually unbroken, アンティーク コイン and the overall shape is still discernible. This grade is often the lowest viable level for a coin to be considered eligible for trading.

Very Good coins have more detail visible than Good coins. The design is clearer, and some of the finer elements like text or fine lines begin to come into focus. The coin still shows substantial friction, but the overall form is clearly outlined.

Coins graded Fine show marked improvement. Most of the design is clearly rendered, and wear is moderate. The high points of the design, such as the cheek on a portrait or the top of a crown, show slight flattening, but the overall image remains distinct and coherent.

The Very Fine grade stands out for clarity. The design is clear with only light wear on the highest points. Details like individual locks, wing details, or tiny glyphs are distinct and readable. This grade is often desired by serious buyers who want a coin that retains strong visual appeal.

Extra Fine shows minimal circulation. There is only tiny abrasions at the peaks, and original surface glow is largely intact. The surfaces are unmarred, and the details are sharply defined. This grade represents a coin that has experienced minimal handling.

AU coins display near-perfect preservation. Wear is limited to the very highest points of the design. These coins retain much of their original mint luster and have no deep scuffs or dings. They are borderline pristine but have been been touched enough to reveal subtle wear.

Mint State represents the pinnacle of coin preservation and refers to coins that have never been in circulation. These coins show no wear whatsoever. They retain their complete mint brilliance and have no signs of friction or handling damage. Mint State coins are further divided into numerical tiers ranging from 60 to 70, with MS-70 denoting flawless condition with no blemishes observable with magnifying tools. Even tiny defects including lint marks, storage abrasions, or patina can alter the assigned level.

Grasping this system is crucial for numismatists, dealers, and investors. It provides a standardized terminology to describe a coin’s condition. This helps build trust in the market. While a coin’s provenance and age also influence its value, condition remains one of the most critical factors. A a unique specimen with severe damage may be worth less than a common coin in Mint State, so interpreting the MS scale correctly can transform your collection’s worth.
