Likely Carmelita had INTERPOL bag and tag them as evidence; they were then, after two years (judging by the fact that Sly and the gang didn't try to steal them earlier), turned over as artifacts with historical significance to the museum. This, of course, suggests that Clockwerk was some sort of myth or legend in ancient Egyptian culture, otherwise why would they want them?
