Luster on US Gold Coins
By Doug Winter – www.RareGoldCoins.com
Gold coins basically come with three types of luster: satiny, frosty and prooflike. In this blog, I’m going to discuss these three “looks” and the pros/cons of each. I’ll also add an illustration of each look. And away we go…
Frosty Luster
The most common luster seen on United States gold coins, especially those from the 19th century, is frosty in texture. Frosty luster can be extremely attractive. I would describe it to the new collector as having a “hard” look and it is most associated, in my experience, with coins produced at the Philadelphia and San Francisco mints.
Frosty luster is considered a “plus” by most collectors. Unfortunately, this sort of luster is becoming harder to find as more and more gold coins are chemically treated. Coins with original frosty luster have what I call a “wagon wheel” effect where the luster flows clockwise and appears to almost radiate out from the center of the coin.
Some of the series that are famous for having above-average frosty luster include the Fat Head quarter eagles and half eagles from the 1820’s and 1830’s, Classic Head gold, No Motto Philadelphia issues and Three Dollar gold pieces.
Satiny Luster
Another type of luster seen on United States gold coins is satiny in texture. Satiny luster tends to be less attractive than frosty luster but it can be very appealing. I would describe it to the new collector as having a “soft” look and it is often seen on branch mint coins from the 19th century and on San Francisco issues from the 20th century.
For the new collector, satiny luster is more difficult to understand and appreciate than frosty luster. This is due to the fact that it is more subtle in its appearance. As an example, the luster on the coin shown above is excellent in-hand and shows very few breaks in the fields. But most collectors would think this coin has a considerable amount of wear; due to its subtle luster and, obviously, the weakness of strike at the centers.
In my experience, satiny luster is more often seen on New Orleans issues, Civil War era gold and some of the Reconstruction era Philadelphia issues. (more…)

Currently, three of the most sophisticated collectors who are widely recognized are Dr. Steven Duckor, Stewart Blay and Jay Brahin. Considerable information regarding their collecting accomplishments is found in the PCGS registry. While Jay is more of a specialist in early 20th century gold coins, Blay and Dr. Duckor have built phenomenal collections in several areas. Not all of their coins are listed in the PCGS registry. Most sophisticated, advanced collectors have similar sentiments and a preference for natural toning. Many of them, however, wish to remain anonymous and thus will not be mentioned. Duckor, Blay and Brahin are all very much willing to share their knowledge with the coin collecting community.
There are a few things about the color of this coin that are a give-away for its originality. The first is the glow that this particular hue of coppery-orange shows. It is the result of over a century’s worth of toning and mellowing of the surfaces. This sort of color just can’t be reproduced by artificial means. When chemicals are applied to gold coins in an attempt to recapture a reddish-orange hue, the result is usually a shade that I refer to as “Cheeto Orange.” In other words, the orange is just too intense to look real and there is no gradiation or seperation of the hues.
