Maybe the seller bought the coin with that picture and just reused it, never noticing the photoshop? It would be funny if there wasn't anything there at all. Although I doubt that to be the case.
This is why it behooves a buyer to see the forest through the trees, or, if you will, see the whole coin, before attempting to identify variety. This kind of stuff is more common than you'd think, especially with rare dates.
I was approaching this from the lens that C-B-D scored a major cherrypick, as usual. As I said, if I was approaching this coin from the perspective of buying it, I would have observed the pictures quite differently.
Hate to admit it so long after someone already identified what was wrong, but I saw that botched MS Paint editing job in two seconds flat.
some years ago I bought a raw Trade Dollar off eBay, I think it was a 74-cc, after I got it realized they had shopped out a blemish in the obv. field where someone removed a spot.
