No way is that mint red still on the coin, an XF would never have that sort of color. It looks like it took an old cleaning and has since turned brown again. Also, it has some verdigris on the reverse.
Very hard to tell. The color of the photo suggests a dipping, but copper can be fickle under the lens, and I've seen perfectly natural coins look odd under the lights. If it is really natural, $100 is a good buy. If it is not, it ain't. Tough call, but with a good return policy, might be worth a shot -- if you have the ability to tell the difference in-hand with a high degree of certainty. If not, then you have no business buying raw in the first place. The coin looks mint state (TPG grade, 63ish details) to me.
Coin looked good to me, almost bid on it but didn't in case some of you here were doing so. I would never ask about a live auction I was interested in here as I'm sure others would run it up.
Unless you told everyone that you already owned it, then I would make you pay a price for lying about it
I don't see it as having been dipped -- at least not in recent time. Dipped coins would have even toning across the total surfaces. But the toning appears to be less in the protected areas around the devices. Can't tell if it's been abrasively cleaned; need it in hand to tell. But IF there's been cleaning it appears to me to be the "wiping" type, not the "dipping". As for the color, hard to say. The seller may not know how to reasonably image coins (lighting, etc.)
