With the current political tension between Ukraine and Russia, I thought it was about time we had a general discussion thread on the Russian ruble.
A currency with a 500 year history, it has endured great social, political and economic changes and several redenominations, most recently in 1998.
The ruble is subdivided into 100 kopeks, and there are currently 35.73 rubles to US dollar. It is legal currency in Russia, South Ossetia, Abkhazia and it is used unofficially in Belarus.
If you have an interest in the Russian economy and/or the Russian ruble, feel free to discuss either of them in this thread.
