I can imagine certain years having collector's item value, such as 1996. Or maybe a year with a WR or AR. But a "just regular" year? Well, I suppose there are always folks in search of historical memorabilia for one reason or another. I can't imagine buying a finisher's medal for a marathon I didn't run, though. Ha, maybe the person who bought the marathon number (if s/he didn't run the race) will buy the medal to complete the "outfit."
