A & B are mistakes, pretty bad but I can see how they happen (A is very close in size and For B the coins are the same colour). The Trade dollar I wouldn't consider an auction mistake but a counterfeiters mistake. Now for C, I can't see that happening, unless he mixed up the photos I don't have any idea how the seller could have mixed the two up. They aren't even remotely the same! C gets my vote for sure.
