AboutMyCoin1927 Mercury Dime (No Mint Mark) in PO1
A 1927 Mercury dime with no mint mark graded PO1 is that coin in one particular state of preservation — the date and the mint mark are already fixed, and PO1 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 Fine (F-12), at $8 to $9, from sales and public data.
What PO1 means
A 1927 Mercury dime with no mint mark in Poor (PO-1) is worn smooth: the coin can be identified as to type and the date can be made out, and that is the whole of what this grade claims. the high points of the wing and the hair above Liberty’s ear are flat to the field, LIBERTY around the cap, the date, and the designer’s AW below the neck have worn away into the rim over most of their length, and what survives is an outline. It is a grade worth having only on an issue scarce enough that a reader wants one in any state at all.
A slab, a dealer’s list or a price guide may write this grade PO-1. They are the same grade and the same 1927 Mercury dime with no mint mark.
Where this grade sits
