I line them up in geographic location.
We try to do that with Christmas ornaments, pick one up for every trip. Somehow we couldn't manage to find a Christmas tree ornament in Rome so we had to settle for a magnet.
I write the date on corks and toss them in an apothecary jar. Some of them are meaningless in retrospect, but sometimes it's fun to pull one out from a special occasion.
