Fine (F) - Moderate to heavy even wear. Entire design clear and bold.
Fine is labelled F-12 in the Sheldon scale. Your average 1965 quarter from circulation is Fine. A lot of the details are gone, but you can still see a good deal of the design.
Very Good (VG) - Well worn. Design clear, but flat and lacking details.
Very Good is VG-8 on the Sheldon scale. The entire design is weak, but a few details are visible. Full rims are nearly always a requirement for this grade. A full rim means that you can see a line around the edge of the coin where it was raised up.
Good (G) - Heavily worn. Design and legend visible but faint in spots.
On some coins, full rims are not required for this grade. You must be able to read the date and mint mark.
