I have several Russian coins. Here are the two nicest, both of which I purchased on Teletrade:
This is an 1839 half-rouble or poltina. NGC graded it MS63. It has nice original surfaces with iridescent tone (I couldn't capture the color accurately in my photos). The strike is a bit soft on the upper right reverse.


This is an 1841 5-rouble gold coin, graded MS-64 by NGC. It has bright gold luster with a couple of obvious copper spots.


The Russian coin I really want is a platinum 3-rouble coin. I've bid on several in various auctions but have always missed the prize. Prices just keep going up on these.
