Could your collection be worth millions?

If you've ever seen an episode of Hoarders on A&E, you know there's a fine line between packrat and connoisseur. Most gatherings of so-called junk are just that, and odds are there's little value to your collection of buttons and "vintage" linens.

Every once in a while, though, a collection can prove to be worth big money. And whether it's stamps, toys, jewels or coins, even the regular Joes among us could be sitting on something special. Don't know what to look for? MSN presents collectors' items that, if you've got the right goods, can be especially lucrative.
