I'm not "into" dice and don't have any fancy ones. I suppose the only ones which have any meaning are my very first non-d6, which are a pair of d20s numbered 1-10 for use as percentile dice. At the time, non-traditional dice (anything besides a d6) were extremely rare. I bought them for wargaming before I was even aware of RPGs. They were one white and one red. I decided that the red would be the 10s and the white one the 1s. Every since then I've always used a red and a white for percentile rolls.
