Experience can be an asset for rating the condition of coins. Vintage coins need to be graded correctly in order to determine a fair value for them. Proof coins are perfect quality mint products and always fetch the highest price in any call auction bids. The coin grading system is classified under 9 grade criterion as listed below:
PROOF COINs have very sharp clear features as they are minted using specially prepared die and blanking tools to produce well polished design features.
Fleur de Coin (FDC) can be graded as Proof Coin, as perfect as the original mint state coins. Such FDC grade coin maintains its full luster without any trace of marking of or abrasion.
Brilliant Uncirculated (BU) coins will maintain full luster without being toned or tarnished. The metallic color tone of circulated coins will definitely deviate from the original tone specification and change to tarnished state once they are released for public circulation.
Uncirculated (UNC) is the grade applicable to coins that do not have visible abrasion or scratches, but are tarnished and with some changes in the original metallic color tone.
Extremely Fine (EF) coins may still maintain some luster and sharp clear features of mint state, but with faint sign of negilible wear.
Very Fine (VF) are applied to coins that rather worn out, maintaining minimal luster around the embossed text script area
Fine (F) coins still show the minted features, but with visible fine scratches or may even have minor indentation on the edges or coin surface.
Good (G) condition coins are not worth collecting unless they are unique and rare. Most of the features on the coin surface are worn out and flattened with some areas being illegible. There may be
small notches or indentation on the edge or surface too.
Poor / Fair (P) coins are worthless for collection as they are almost completely worn out and usually beyond recognition, except for the faint design outline.
