Guess the grade--1924 NGC St. Gaudens Double Eagle

A valid point about which part of his comments ? Ya see, wear can easily be distinguished from a weak strike by those who know how. And on that coin it's wear. Even Paul said so and he has/had the coin in hand.

So how do ya tell wear from weak strike ? It's actually simple but most just aren't aware of it. It's the texture and color that allows you to do so. A weakly struck area will have a certain texture to it, it'll be rough and bumpy to a limited degree. This is because the metal is being pushed up, or down, (depending on which side you're talking about) in an effort to fill the recesses in the die. But the metal never quite gets there because there just ins't enough pressure for it to do so. The end result is that slightly rough and bumpy texture in the weakly struck area. You have to look close to see it but it'll be there every single time - if it's a weakly struck area. The second diagnostic is color. A weakly struck area will be, usually, greyish in color, or at the least a bit darker in shade than the rest of the coin that has luster. And that's the 3rd diagnostic of a weakly struck area - there will be no luster there. That's because the metal in that location never touched the die so it never had a chance to flow and create the luster there.

With wear, it's a little different. The area will be darker than the rest of the coin that has luster, again usually greyish in color - and that grey will be slightly darker than a weakly struck area will be - just slightly. So it takes experience to be able to recognize the color difference when you see it. And of course there will be no luster in an area with wear. And, there will be no texture to the surface. It will smooth, often even flat, depending on degree.

And that, well that's why he doesn't make a valid point, at least on that specific issue.

Understand Cheech ?
