Link works when copied and pasted above. Real or not - difficult to tell from the picture alone0 .16 grams short of weight (~5%) can be explained by wear. Strange thing that it was inserted at $.99. The seller hasn't sold any rarities before, looks like an antique dealer. But one never knows.... Let's see the buyer's feedback. Someone ready to risk that heap of money for a - well, ugly looking coin most have some experience. In my opinion a coin like that needs to be seen in person, taken in hand, inspected closely.
