AboutMyCoin1931-D Mercury Dime in F12
A 1931-D Mercury dime graded F12 is that coin in one particular state of preservation — the date and the mint mark are already fixed, and F12 is what a grader called the surface that survived. What that looks like on this coin is below. The nearest grade of this date this site does have a researched figure for is Very Good (VG-8), at $16 to $38, from sales and public data.
What F12 means
A 1931-D Mercury dime in Fine (F-12) carries moderate wear over the whole coin, but the design is still a relief rather than an outline: the high points of the wing and the hair above Liberty’s ear keep some separation, the horizontal bands across the middle of the fasces and the tops of its rods are worn smooth at their highest points while the outline of every feature stays sharp, and LIBERTY around the cap, the date, and the designer’s AW below the neck are full and clear.
A slab, a dealer’s list or a price guide may write this grade F-12. They are the same grade and the same 1931-D Mercury dime.
Where this grade sits
The grades a 1931-D Mercury dime is given run from PO1 to MS70. One step up from F12 is Fine (F-15). In general terms, the higher the grade the more the coin is worth.
A blank in the value column is a grade this site has not researched, not a grade the coin is worth nothing in.
