My grandma sold her AZLK 2140 Moskvitch car around the time of breakup of Soviet Union and put all the roubles in bank deposit for me and my brother. Few years later we got it, due to inflation and money reforms with interest it was around 2-3 lats for each of us, which is something like 5 euros (when euros were introduced later, exchange rate was approximately 1 lat = 2 euros).
