Well, as of this moment, and if that is a Ruble (or should I say 5000 rubles), it's worth 174.768 USD.
http://www.xe.com[Edit] Upon closer inspection, and checking for images of russian rubles, it is in fact a 5000 Ruble Note. Here's a pic of a
100 Rubble Note the Russian two-headed eagle in the upper left corner on the front.
[Edit AGAIN] Sorry.. that's an OLD 5000 ruble note.. Remove 3 Zeros's to get the current worth, 5 Rubles, which converts to 0.174710 USD, or .17 cents. Sorry to get your hopes up.
