How about an absolute max of four for only the most world-changing events in history, with a significant enough fallout to surround them. Three the max for your average wikipedian, two still unlikely but quite more possible and a single artifact for everyone and everything else. I'm of the opinion that every person will likely create at least one artifact during their life, with effects that may be too minor or specific to ever be noticed.
