What do G, VG, F, VF, XF, AU and UNC mean? 

G, VG, F, VF, XF, AU and UNC are grades, signifying how a particular coin is worn and how much of the original details remain. Those letters are abbreviations for:

  • G: Good
  • VG: Very Good
  • F: Fine
  • VF: Very Fine
  • XF: Extremely Fine
  • AU: Almost Uncirculated
  • UNC: Uncirculated

 

There are also lesser grades, not represented on Numista: 

  • PO: Basal State or Poor
  • Fr: Fair
  • AG: About or Almost Good

 

On Numista coin pages, you can also encounter Proof and BU coins. Both are made a little differently from standard coinage. Details can differ from mint to mint for both.
