Help With (Maybe Russian) Banknote

Russia, 10 rubles, 1909 model but issued until 1917.

It is not particularly valuable, these notes can be bought on ebay for a few dollars.

Sorry for late answer, but a bit more detailed info.
Note series - "DO" says it's official issue of Empire Government, not Provisional Government or later Soviet issue. This is good.
Note is in poor conservation but when approaching one of these notes please pay attention to signatures. There are two of them - upper signature belongs to Manager of Bank - at this example it's "Shipov" - very common one. Lower signature put by teller of the Bank. There are 13 different teller's signatures available and some combinations of Manager and Teller signatures are considered not common or even rare issues and might have certain value. This note is signed by teller "Baryshev". Combination "Shipov" + "Baryshev" is common with price up to $1. Other Managers - "Timashev" or "Konshin" would be a bit more valuable. Well none signature combination is Manager "Konshin" + Teller "Brut" and normally these notes are valued more since they were believed to be a lucky one. Even professional poker players from ex-Russia sometimes carry in the wallet a so called "Brut rouble" :)

Thanks David. You're always welcome.
