Fleur-de-coin (FDC) Flawless, a term generally only applied to ‘Proof’ coins.
Uncirculated (UNC) or ‘As Struck’ A coin that is in the same condition as it was when issued, with no wear through circulation at all. The term ‘Brilliant Uncirculated’ is sometimes used to describe an Uncirculated coin with full mint lustre or brilliance, and Choice Uncirculated to describe a coin which has no or only minuscule imperfections.
Extremely Fine (EF) A coin that shows very little evidence of being in circulation. Faint wear, typically to the high points of the design, may be discernible through close inspection/under magnification.
Very Fine (VF) A coin that has had limited circulation but shows some wear to the high points of the design.
Fine (F) A coin that has seen considerable circulation and therefore has considerable wear to the raised surfaces of the design.
Fair A worn coin where only the main features and legends are still distinguishable.
At times the wear to a coin is progressive and does not occur in steps (EF, VF, F) and the price that any given coin commands does not follow change in steps either. Therefore Middlesex Coins use the well recognised terms:
Good: better than e.g. Good VF Nearly: not as good as e.g. Nearly EF
The terms ‘almost’, ‘about’ and ‘virtually’ can also be used which imply ‘closer’ to a grade than ‘nearly’.
