At a garage sale (February 1997), I picked up what appears to be a 1909 10-Ruble bank note.

A page on the Internet suggested a 1909 10-ruble bank note might currently be worth $2.00.
Another document from the net stated that
"The gold standard was established in January 1897 with 1 Ruble = 774.234 milligrams of fine gold. Gold convertibility was suspended in July 1914."
Here is a loose translation of what is on the banknote, courtesy of Bryan Fugate:
The State Bank will unconditionally exchange this banknote for gold.
1 ruble = 1/75 of an imperial (gold coin) being valued at 17.424 portions (grams?) of gold.
