I don't know anything about gold commems but I assume the granular areas are caused by die wear. Looks premium gem to me and the color, especially the reverse, is spectacular. As a Jefferson collector, this coin is on my list, and I would love to own this particular example.
I assume the granular areas are caused by die wear.
this was my initial impression until i considered the "Orange Peel" effect which is well documented on certain specific issues from this era, most notably Gold Proofs. i wondered if this might be an example of that appearance.
The surfaces of Jeffersons frequently show disturbed areas resulting from die wear, this actually shows less than most I have seen. It is not what most refer to as orange peel texture, which is a result of proof stiking.
not my coin, i was just wondering about the Orange Peel. Bill, what are the telltale signs of "iodine" on the surface?? i've heard of that but never really have had it explained insomuch as how it's done and what the desired affect would be. i assume it's either to enhance something or to hide something.
I see telltale signs of some sort of liquid in the fields around two o'clock and eleven o'clock on the obverse. If you look at the fields in those areas (and other parts), you will see what appears to be light marks, covered by the iodine. Also look at the shoulder of Jefferson. It looks like a pretty serious scratch has been covered up. Tilt and rotate the coin at the same time. I suspect that the difference in colors on the surface will become more apparent.
As I've said many times before, it is virtually impossible to grade from a photograph. But in this instance, with a little knowledge of the coin business and unethical practices of certain dealers you can make an educated guess.

Agree---appears like an nicely toned original gold coin but without an in-hand examination I can't be sure that it wasn't helped. Also, that's die erosion and the lack of denticles on the reverse indicates that this coin wasn't fully struck. Die erosion and weak denticles are typical for this issue and, overall, it appears to be a decent coin.

I don't think the die erosion should be any factor in evaluating this coin. While many collectors might not like that look, that is the way it was made. The surfaces, on the other hand, are not indicative of Mother Nature's work. Just some humans.
looking at these two from the same time period, i wonder if the Sesqui would be judged the same as the Jefferson?? it appears to have similar inconsistent surface color which i had always just assumed was tone/copper while the Hudson has even color throughout.
At first I was going to say it was a delightful, orange peel effect coin, worthy of a plus, a sticker, and a sniff. However, I am intrigued by NJCC's iodine theory. Very interesting.

I thought that iodine was used to make gold look darker and more crusty. The idea was to cover up marks and perhaps make pieces that had been dipped to be "white gold" look more original.
Maybe I'm wrong, but that was my impression.

Great comments in this post. Keets - you are a pretty sharp guy and I assume the reason you posted this asking about the surface of this gold piece is because something caught your eye or hit that little intrigue button. Listen to your instincts. Gold pieces are boinked more often than many think. A few smart guys have responded to this with a little skepticism. That isn't just coincidence.
Maybe I'm wrong, but could the white / light colored areas on this coin be due to trace amounts of silver that has come to the surface. I know that gold and silver are found together in ore, and one of the purifying processes is to treat the ore with nitric acid to remove the silver. The gold is not attacked by the nitric acid, but the silver is removed in the form of silver nitrate.
One of the reasons why some Charlotte and Dahlonega gold coins have a whitish or greenish shade is that there is still a fair amount of silver in the 10% side of the usual gold alloy (90% gold 10% copper and often some silver). Therefore perhaps we are seeing the affects of tact amounts of silver in this piece.
I also know that the 1903 Jefferson and McKinley commemorative gold dollars can have more than there share of copper spot problems. It’s far worse for the 1926 Sesquicentennial $2.50.
I’m throwing this out as a possible explanation, not a fact.

Mushy denticals is not unusual for this coin. I had one years ago with a similar situation and saw a number of others when I was shopping for the one that is now in my collection.

I'm certainly no expert on gold but that is a very nice looking commem you have there.
