AboutMyCoin1942-S Mercury Dime in G4
A 1942-S Mercury dime graded G4 is that coin in one particular state of preservation — the date and the mint mark are already fixed, and G4 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 $7 to $8, from sales and public data.
What G4 means
A 1942-S Mercury dime in Good (G-4) is worn evenly across its whole surface, and the design reads as an outline rather than a relief: the high points of the wing and the hair above Liberty’s ear are flat, the horizontal bands across the middle of the fasces and the tops of its rods show no detail at all, and LIBERTY around the cap, the date, and the designer’s AW below the neck are still readable with the rim beginning to merge into the lettering.
A slab, a dealer’s list or a price guide may write this grade G-4. They are the same grade and the same 1942-S Mercury dime.
Where this grade sits
The grades a 1942-S Mercury dime is given run from PO1 to MS70. One step up from G4 is Good (G-6). 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.

Whatever the market does, a 1942-S Mercury dime cannot be worth less than the metal in it. That figure is what the premium for G4 is measured against, and it moves with the metal price rather than with the coin market.
