In the July 16, 2025, issue of the Metropolitan Coin Club of Atlanta’s Newsletter, the From the Desk of the Editor column, titled Understanding AU-58 and the Nuances of Coin Grading, introduced three seminal articles by Bill Fivaz exploring the importance of AU-graded coins. As announced, these articles—AU-58: The Grade of the Future?, Almost Unlimited Bargains in AU, and It’s Confession and Revelation Time!—are being reprinted in full on our website and will appear in the club’s next three consecutive newsletters, presented in the order of their original publication. We are pleased to begin this series with AU-58: The Grade of the Future?, a foundational piece that examines the growing significance of AU-58 coins in the numismatic world. Dive into this article to explore the origins of Fivaz’s perspective on AU-graded coins and stay tuned for the subsequent articles in this series.
Have you been just a wee bit confused as to why one particular coin in a certain grade sells for a great deal more than another coin of the same date in the same grade? Why does one MS-65 1882-O Morgan dollar, for example, sell for $650 while another, also a legitimate MS-65 specimen, bring only $400?
While both of these coins might technically grade MS-65, the specimen that garners the higher price probably has that “something” extra in the way of toning and appearance—eye appeal! No two coins are exactly alike (a nick here, an abrasion there); each must stand on its own merit and therefore may command a higher (or lower) price than the one “listed” for that grade.

The point is that there are MS-65s and there are MS-65s, just the same as there are different qualities in the grades of MS-63, Fine (F), Extremely Fine (EF) and, most important in my opinion, About Uncirculated (AU).
The quality grade in the AU range is at least AU-55 and more specifically, AU-58. So that we know what an AU-58 coin really is and what it actually looks like, let’s define it. I suggest the following: “AU-58—a coin that when first observed, appears to grade MS-64 or MS-65 (good luster, few contact marks), but on closer examination reveals slight wear on the highest points.”

A common misconception is that a high-quality AU-58 “super slider” is just a hair away from an MS-60. Nope! In reality, it is much closer to an MS-64 or an MS-65 with just a touch of honest wear. It jumps right over the MS-60 grade because of what makes an MS-60 an MS-60—lots of contact marks, impaired luster (or a combination of each), and, in general, no real eye appeal. Add the same amount of honest wear to a coin such as this and you have an AU-50.
Is AU-58 the grade of the future?
Why not? MS-64 and MS-65 coins (and soon MS-63) have, for the most part, skyrocketed in price into the stratosphere and properly graded, very choice AU pieces are currently the bargains of the century!
Think about it. Top quality AU-graded pieces are much more attractive and priced far less than MS-60s. Someday someone is going to see the light and realize that many, if not most AU-58s, and even some AU-55s should command a price in excess of MS-60 listings! I don’t know when this will happen* but believe me, they’re worth it. Don’t hesitate to pay a hefty premium for a nice, eye appealing, choice AU coin—in the years ahead you’ll be glad you did.

Learn the first points of wear on your series and on some of the popular issues. Look for a loss of detail from wear in these areas as well as a difference in color, usually dull and flat in the same areas. Remember, an AU-58 coin must have MS-64 or MS-65 luster and a corresponding lack of marks in addition to just that little bit of wear.
If you can locate these coins, properly graded at an AU price, grab them, especially type coins and pre-1935 modern issues. Plain common sense dictates that these are the coins of the future—the ones collectors will seek to complete their sets without having to pay big bucks for the MS-63s, -64s and -65s.
*This article was written for The Numismatist in 1986 and this prediction has come to pass. Many technically AU-58 coins now reside in MS-61 and MS-62 holders as this is the price they are commanding in the market.
