For Fine (F), there will be about 50% of the original detail visible.

Or, on a coin with no inner detail, there will be fairly heavy

wear over all of the coin. Sides of letters will be weak. A typically

uncleaned coin will often appear as dirty or dull. A small grading

area will have just under 50% of the original detail.

The Very Fine (VF) coin will have about 75% of the original detail

visible. Or, on a coin with no inner detail, there will be moderate wear

over the entire coin. Corners of letters and numbers may be weak. A

small grading area will have about 66% of the original detail.

On the Extremely Fine (XF or EF) coin, there will be about

95% of the original detail visible. Or, on a coin with a design with

no inner detail to wear down, there will be a light wear over nearly

all the coin. If a small design is used as the grading area, about

90% of the original detail will be visible. This latter rule stems from

the logic that a smaller amount of detail needs to be present

because a small area is being used to grade the whole coin.

For Uncirculated (Unc.) grades there will be no visible signs

of wear or handling, even under a 30-power microscope. Bag

marks may be present.

For Brilliant Uncirculated (BU) grades there will be no visible

signs of wear or handling, even under a 30-power microscope. Full

mint luster will be present. Ideally no bags marks will be evident.
