What F12 means
A 1927 Mercury dime with no mint mark 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 1927 Mercury dime with no mint mark.
Where this grade sits

What it sold for
No certified sale of a 1927 Mercury dime with no mint mark in F12 is recorded in the sources this site reads, which is what you would expect at this price: certifying a coin costs a large share of what this one is worth, so almost all of them change hands raw and unrecorded. The range above is what the published guides say rather than what anybody paid, and it is the weakest figure on this page.
