AboutMyCoin1931 Mercury Dime (No Mint Mark) in G4
A 1931 Mercury dime with no mint mark 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 Fine (VF-20), at $11 to $19, from sales and public data.
What G4 means
A 1931 Mercury dime with no mint mark 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 1931 Mercury dime with no mint mark.
Where this grade sits
The grades a 1931 Mercury dime with no mint mark 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.
