I should've done this before I posted the grades but here's a couple of better photos of the 1870 through a loupe. It looks like someone bit it to see if it was real.
50 and 35 I have almost the same 1870g California gold 1/4 dollar, the only difference is mine is round.
My guess of the California would have been completely different with those second pictures. The damage is plainly obvious now.
