OK, I'll bite in the interest of learning.
1) Surface porosity, especially the large recesses in the fields.
2) Weakness in the middle of the wings and bottom of the tail.
3) General lack of sharpness at the intersections between devices/letters and fields.
4) Feedback from buyers in this seller's record which was posted less than 24 hours after the sale. DINGDINGDINGDINGDING
I do not know the specific issue at all, so I can't comment on design irregularities.

SuperDave Super Dave.
There is only one other major item that you missed. I will answer if no one gets it.

The pourous surface, the rim looks like it is rolled up an the devices are too round or balbous and I would assume there would be die mark hole or entrance I am not sure how to describe what I mean. Like an injection mold there will be a spot on the coin that shows up wher the liquid metal was pored through the mold. I hope some one can make sense of what I just said.
Do we have any one who can translate gibberish to English. LOL

To me it looks like the lettering is worn toward the center of the coin, not toward the rims.
Scout I know what you are trying to say, you mean the little rough patch where the mold was injected, like near the edge of a CD case or the bottom of a pop bottle?

Ok I'll bite. The only thing left I can see that hasn't been mentioned is the rim on the reverse at around 6 o'clock looks to have some material splash in the ridges

Could be, the picture gets blurry when you blow it up so it could be the molding site it's hard to tell. I work in manufacturing and when we do castings on a sensitive part we have to inspect (under a microscope) for material splash in certain recess areas that will hinder component performance. Can't tell you how many times I've been tempted to slide a coin under that microscope!

OK - lots of nice observation.
The rim is the dead give away. The rim is simply too high for a strike in a screw press.
When an open sided screw press impacts a planchet it does NOT raise a wire rim. That only happens in a closed collar press where the force of the strike raises the rim up when the outward force encounters the immovable object the collar ring.
The counterfeiters not being familiar with open collar strikes often roll the edge of the mold (they smooth the mold rounding the edge of the mold at the joint with the edge mold - like you see here. replicating a wire rim.

on the reverse near I'm on th right near the wing there is what appears to be a hole and some striation marks (Fake I Assume to make it more like the metal in a coin that was in a screw press) I think is that the injection site and did anything I said in this post or the others make any cents-LOL. excuse the pun. I am looking for feed back for my own personal understanding and learning. Great lesson BOB Thanks. And can you give us another one.

Thank you, swamperbob. The rim is a dead giveaway that I'd never have known, not being up on screw press operation. Guess it's time to learn.

Hi Jim,
The feature you point out is a casting void - the first I noticed. You are right that it should not appear on must struck coins. (The one exception would be a coin struck on a cast planchet. But even in that case, the void would clearly show the effects of being squashed by the strike.) Anyway, the lines near that feature are not associated with a screw press strike. They look more like they might be a finger smudge on the soft surface of a molded transfer casting before it set fully. In person, that feature might be a real tell-tale feature. Of course it could be a toning anomally caused by a finger print (or smudge) as well.
The key traits - are the air bubbles cast into the surface and the improper rim. The central weakness of the designs, the poor transitions in the letters and other features and the color are all anciliary features that confirm the diagnosis.
