It looks funny to me on the reverse, but it could just be the die state... I have no idea. Plus, it's toned gold (or dirty) , which seems weird to me.
It looks genuine to me though the coloring is strange. Gold does tone and can get dirty, as much as people hate to admit it. And these are pretty notoriously weakly struck,
I am certainly no judge of gold dollars, but why does the 4 in the date look like it's stuck on with epoxy?
Reality is no one can tell a good fake from just a picture. Only clumsy fakes can be detected that way. What is the weight in grams to the second decimal place on a calibrated scale? A pinprick of Nitric acid on the rim will also tell much. What is the size of the coin in mm? Cleaning agents can change gold coin color so if the color is wrong, that could just mean someone for whatever reason dipped it. Likewise I rarely see on my own uploaded photos a coin image that is the exact shade and tint of the real one in my hand. Monitor quality, available gamma at time of photography, camera quality, and line noise all have an effect what we see, so hold off on color alerts till you have it in front of you. 1874 was a high production year. If it said 1875, then epoxying a number on would make more sense, but for a 74? What'd they do? Scrape off the 5 and glue on a 4? LoL. It looks from the pics like a fairly standard $200 gold dollar, maybe VF.
I've seen a fake one of these before come in and even though I'd hate to say it but JUDGING BY THE PIC PROVIDED I'd say it's pretty close to the fakes I've seen. But don't get me wrong it could be very real with a weak die!
The coloring is off and the reverse looks a bit strange. It looks pre-hucky to me and gold don't get hucky. My guess is it's a fake.
I don't care for the surface, I would worry about a cast coin or spark erosion dies ( non-mint) producing the pips an dips.
