Newbie coin collectors are often overwhelmed by the words and phrases they come across in their new hobby.

While the following abbreviations and acronyms are not the only ones that you will stumble upon when collecting coins, these are the most common ones when it comes to discussing coin grades.

Coin Grade Letters Explained

The letters represent the circulated grade of the coin and various strike characteristics.

These are the most common coin grades:

AG: Almost GoodA grade that refers to a coin with very heavy wear. Most collectors do not collect coins with this amount of wear, except for coins which are considered rare.
AU: Almost UncirculatedA coin which has only slight wear on its highest points.
BN: BrownRefers to brownish hues or toning seen on copper coins.
BU:Brilliant UncirculatedAn uncirculated coin which has notable luster quality and, sometimes, refers to an uncirculated coin with good strike.
CIR: CirculatedA coin which has seen wear through circulation.
CLND: CleanedA coin which has been cleaned or otherwise washed.
DCAM: Deep CameoRefers to a proof coin on which the designs are heavily “frosted” (white).
DMPL: Deep Mirror Proof LikeA coin which is not actually a “proof” specimen but has reflectivity and mirrored surfaces which resemble proof quality. These coins are highly appreciated by collectors and investors alike.
EX or XF: Extremely FineA coin with light wear and has all basic details visible. Higher-level “EF” or “XF” coins often show light traces of luster.
F: FineA coin with heavy wear. “Fine” coins usually have full rims and all major details are intact.
FR: FairA coin with very severe wear. Some people will collect “fair”-quality pieces for coins which are very rare, as is the case with very early half-cents and large cents.
G: GoodA coin with considerably heavy wear. This is considered the lowest grade collectible for “common” coins.
MS: Mint StateAn coin which has no wear and is otherwise deemed “uncirculated.”
PO: PoorA coin that has suffered extreme wear and can often be identified only by denomination and type. Dates, lettering, and detail are often worn beyond recognition on Poor coins.
PR: ProofA coin that has been manufactured specifically to produce an exquisite strike and surface quality. These are usually marketed by the mint as collector coins and often are struck multiple times. Modern-day proof coins have mirror-like surfaces.
RB: Red-BrownRefers to the mixture of red-orange and brown hues seen on copper coins.
RD: RedRefers to the deep orange and reddish hues and toning seen on copper coinage.
UNC: UncirculatedA coin which has never seen any wear through circulation.
VG: Very GoodA coin with moderately heavy wear. A “Very Good” coin typically has full lettering near the rims of the coin. The word “LIBERTY,” when it appears on late-19th and early-20th century coins on a headband will often show approximately 3-4 letters.
VF: Very FineA coin with moderate wear. All major and many minor details are seen. All lettering should be complete on most coins.
