For many eBay sellers, their businesses began as an offshoot of a hobby. If you’re a collector, chances are whatever you collect is actively bought and sold on eBay. And anywhere there’s buying and selling, there’s a business opportunity!
What kinds of things do people trade on eBay? Just about anything imaginable, from antiques to vintage clothing to comic books to HO trains to political buttons to sports cards to glass milk bottles to Hummel figurines to plastic model kits to pocket watches to Barbie dolls to...well, you get the picture. Just as there are numerous bricks-and-mortar stores that specialize in various types of collectibles, there are also many eBay businesses that are collectibles-based.
