AboutMyCoin1919-S Mercury Dime in AU58
A 1919-S Mercury dime graded AU58 is that coin in one particular state of preservation — the date and the mint mark are already fixed, and AU58 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 Mint State (MS-60), at $118 to $317, from sales and public data.
What AU58 means
A 1919-S Mercury dime in About Uncirculated (AU-58) is as close to uncirculated as a circulated coin gets: the lustre is nearly complete and the only wear is a faint rub across the high points of the wing and the hair above Liberty’s ear that shows when the coin is tilted under a light. Many are better-looking coins than a low mint state example of the same date, and they sell for less.
A slab, a dealer’s list or a price guide may write this grade AU-58. They are the same grade and the same 1919-S Mercury dime.
Where this grade sits
The grades a 1919-S Mercury dime is given run from PO1 to MS70. One step up from AU58 is Mint State (MS-60), at $118 to $317 — which is what a reader whose coin might grade a point higher is really asking. 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.
