I've been collecting these since 2000. I have every year from 2000-2006. I was looking on eBay to get the ones from the 90's and OMG are they ever expensive collectables! The one from 1991, is going for $700! They're only $60 new. The ones from 1999 are going for around $250. Maybe if any of you girls/guys have any of these from the 90's, you might want to cash in or hold out. I'm hoping my 2000's collection will be worth something like that one day!
