Very nice Rupees, I also collect "The Raj." Your George V's I would put at around 45. The Willie about a 30.
i would put your 1888 at F 1942 VF i graded his william rupee at VF purely because of its age and the fact that they are extremely scarce in better grades. incidentally the victorian rupees are about the easiest to find in XF to UNC (and not chinese forgeries)
Nice Lot ……… The two George V coins, XF details, but both look like they have cleaned somewhat. The 1835 say VF, but it has been overly cleaned. Not uncommon, with early silver from India. At least that’s what I see in your scans. Interesting post.
