Hi, what's happened with smurfs resembles what happened to American baseball cards in the mid-1980s. A few of them become valuable, so every Tom, Dick, and Smurfy believes all his smurfs, no matter how chewed up or common, command a fortune in re-sale.
I visited a flea market in town ("an antique shop") and discovered, in a locked case, a basket of smurfs. Upon perusing the collection, I noted numerous vintage, though relatively common, smurfs--in various states of repair--all selling for for an average of $12. A chewed-up bicycle supersmurf (40501), with nary a plastic base nor box, priced for $18. The vendor had several baseball catchers each going for $45. I know the catcher is uncommon, but I wasn't impressed, especially since rarer smurfs, like baseball smurfette fetch that price through Mushroom Village.
Well, my point is--everybody thinks every smurf out there is worth a fortune. It's kind of irritating for us hoping we'll find a bargain at the garage sales.
