I had a Russian friend in college. He gave me what seemed to be quite a few Rubles (bills and coins). I asked him how much it is worth, and he said I could probably get a big mac with it. I tucked the money in a drawer (in 1996) and a few years ago I thought about them. I looked up the exchange rate and I couldn't believe my eyes. It was over a grand! Looking further into it - Russia changed their Rubles. Mine were now worth practically nothing I still have them just to have them. They are pretty neat to look at.
