Somewhere between 50¢ and $1, but as always it depends on the buyer. I note a couple of spots and a bit of environmental damage on the rim at 2 o'clock on the obverse which I think would make most folks pass by this coin.
It's not bad. A few spots. Pretty typical. Not a high-dollar coin by any means (I concur with @alurid's general comments), but I've seen worse.
