Not very many, but some are, for example
https://www.geocaching.com/track/details.aspx?id=3330833 - currently in Germany, still trying to find its way home to Hungary
https://www.geocaching.com/track/details.aspx?id=3330812 - is currently visiting Czechia
https://www.geocaching.com/track/details.aspx?id=3330848 - is (hopefully) sitting in a cache in Sweden
https://www.geocaching.com/track/details.aspx?id=5512434 - got mailed back to its owner and retired after visiting Australia and covering 35,626.7km (22,137.4 miles)
Many lost their lives early in the race, being picked up by newbies, who did not bother to place them in another cache after losing interest in the game. :-( Some simple got stolen, some disappeared together with the cache.
