I think it might be that way with most collectables. Sometimes you can sell it for a good amount and other times it's not as valuable. On Antiques Roadshow they've mentioned several times about that kind of thing. It all depends on what is "in". So there may be times when AG or certain AG items aren't as sought after/ valuable, but then later on they could be the "hot" item for collectors.

And I don't think comparing them to Beanie Babies is exactly fair. The markets seem different to me. Plus with AG you not only have the doll collectors, but collectors of miniatures and maybe collectors of historical things (for the older AGC items) and other collector groups may find certain things they'd want (in the future of course, I still think it's kinda too soon to really consider AG a collector's item even though I know some people do collect them)... I don't think Beanie Babies have quite the same potential for appeal.
