When a coin is described as XF40 or XF45, those letters indicate its condition. XF stands for Extremely Fine and is used for coins that have circulated but still retain much of their original design detail.
Within the numerical grading scale of 1 to 70, the XF category comprises grades XF40 and XF45 . It is above Very Fine (VF) and just below About Uncirculated (AU).
What does XF mean on a coin?
XF stands for Extremely Fine . It describes a coin with relatively light wear from circulation, especially visible on the higher parts of the relief. Despite this wear, an XF coin retains a great deal of detail. The figures, lettering, and other main design elements remain clearly defined.
The category is mainly divided into two grades:
XF40: Shows visible wear on the high points of the design. Some may begin to look slightly flat, and little or no original luster remains.

XF45: Shows less wear. Details remain more defined and may still retain some minting luster in protected areas.

As a general guideline, PCGS has described XF40 as retaining approximately 90% of its original details and XF45 as retaining around 95%. These percentages should not be interpreted as a mathematical formula applicable to all coins, as each design exhibits different levels of wear.
Do XF and EF mean the same thing?
Yes. In numismatics you may also find the abbreviation EF , used for Extremely Fine or Extra Fine.
Therefore, designations such as:
XF40 = EF40
y
XF45 = EF45
They essentially represent the same level of conservation.
NGC currently uses XF in its scale, while both abbreviations may be found in catalogs, numismatic literature, and certifications. Therefore, recognizing both XF and EF is useful for any collector.
How to recognize an XF coin?
The main indicator is wear from circulation . An XF coin can no longer be considered uncirculated because its highest points show evidence of contact and loss of detail. However, this wear is still relatively limited. When examining a coin that is a candidate for XF, three main aspects should be considered:
Wear at high points
The highest points of the design are usually the first to show wear. On XF45, this wear should be slight, while on XF40 it may be more noticeable and even cause some flattening. The exact points to examine depend on the design of each coin.
Amount of detail preserved
An XF coin should still clearly display its main features. As wear increases and more detail is lost, the coin may be reclassified into lower categories such as Very Fine.
Coinage luster
On an XF45 coin, some original luster may still remain, especially around lettering, devices, or protected areas. On an XF40 coin, very little or even no visible luster may remain.
Is an XF coin uncirculated?
No.
This is a fundamental difference. An XF coin has circulated and shows wear . Coins considered Mint State , identified by grades MS60 to MS70, do not show wear from circulation. A coin can retain virtually all of its design and still be classified as XF if there is sufficient evidence of wear on raised areas.
What does XF Details mean?

XF Details is not the same as XF40 or XF45.
When a coin receives an XF Details designation, it means that the level of detail it retains is approximately equivalent to the Extremely Fine grade, but there is some issue preventing it from being assigned a conventional numerical grade. These issues may include cleaned surfaces, corrosion, environmental damage, graffiti, or other alterations.
For example, a coin may retain enough detail to roughly correspond to XF, but have been problematically cleaned. In that case, it may receive an XF Details designation instead of XF40 or XF45.
Does the XF grade affect the value of a coin?
The condition can influence numismatic value, so the difference between VF, XF, AU , or Mint State can be relevant. However, XF does not automatically mean that a coin is rare or valuable.
The value can also depend on factors such as rarity, demand, availability, mintage quality, and the specific characteristics of the coin. Two coins graded XF45 can have completely different values if they belong to different issues. Therefore, the grade should be understood as a description of the condition and not as a direct measure of price.
What should a collector remember?
XF stands for Extremely Fine and represents a circulated coin that still retains much of its original detail. The two main grades are XF40 and XF45 , with XF45 being the better preserved of the two. XF is above VF and below AU.
It may also appear as EF, and an XF Details designation should not be confused with a conventional numerical grade. The essential idea is simple: an XF coin shows wear, but still maintains a high level of detail and a well-preserved appearance for a piece that has circulated.
