As usual, most eBay sellers seem to make lousy photographers!

Besides, it is really impossible to grade a coin accurately from a picture.
I can't tell much of anything about the Romanov rouble from the picture, so I will abstain from commenting on that one. When you receive the coin, maybe you can take better pictures for us?
All of the pictures of the 1899 ten roubles gold coin seem to be out of focus, perhaps purposefully so in an effort to hide the numerous marks and scratches one can see anyway. It is especially annoying that the photo of the edge reveals nothing about which mintmaster initials are engraved there. I would grade it only VF, without the scratches maybe XF -- a coin of this type and year in this condition would normally sell for about melt 3 or 4 years ago, but today the prices have inflated terrifically. I would have waited to find a better coin for the price you paid; 1899 is one of the most common years for this type. Hopefully you will receive a genuine coin ... there are very clever fakes out there. Be sure to weigh it when you receive it.
I like the 5 rouble gold coin the best; however, there seems to be a lot of rub on Nicholas' ear and some rub on the hair, so it will probably grade about XF/XF+.
