Nice piece! I'm no professional but if I had to venture a guess I'd say F-15/VF-20 or thereabouts. There still appears to be some good detail on the reverse eagle crest. How much did that set you back if you don't mind my asking?
Russia, 1900, 1 Rouble, metal- .900 silver, weight-19.9960 g. or .5786 oz. mintage-3,484,900 , struck at St. Petersburg without mint mark. 19 century Krause World Coin Catalog- Y#59.3 grade/value F-$15.00 VF-$30.00 XF-$75.00 UNC-$325.00 I would guess your coin looks VF. a Russian coin collector could tell what grade your coin really looks like. nice early common date.
Coats of arms on the eagle look worn, hard to say much from these photos. The other side got too much wear on the ear and hair, so yes, VF. $45 is exactly what it is worth.
Keep it long enough on eBay as BIN and it will go for $60-70 eventually. Doesn't mean it is worth that. IMHO $45, $50 top (from these photos).
I checked NGC book value and it says $180.00 for VF? The angels of the pics are terrible, and I mean it could be in BU condition.... okay nvm not BU, but could be better than it looks. I don't have the coin yet, it is in the mail to me now. I will throw up real pics of close ups when I get it in a few days.
