I was skeptical when I first opened the thread, but after trying to attribute the coin I think they are right.
It is definitely a large fraction reverse. That only comes on 1803 S-257, 258. 259, 260, 261, and 265. And on 1804 S-266, and 1807 S-275 and 276.
S-257 is out because it has six berries on the left branch, all the rest and the OP coin are missing the outer berry below ST.
Of all the rest of the varieties the berry to the right of the E in ONE is at the top of the E. ONLY on the 1804 S-266 is that berry opposite the center of the E as on the OP coin.
So what did it go for?
