Collectibles for the gullible
A bobblehead doll is exactly what it sounds like: It’s a doll where the head bobbles when you shake the table or tap on it. The dolls as we know them were first made in the 1950s. Major League Baseball first made a paper-mache bobblehead doll for each of its teams in the 1960s.
Today, they're popular giveaways, not just for MLB teams, but for other professional sports, as well. They're fun, but they're not collectibles into which you should sink big money. They rarely become more valuable than the price of your admission ticket.
Sure, some of those 1960s dolls sell for more than $100 on eBay, but if you're spending $50 or $75 today for a ticket to a game with a bobblehead giveaway, you might not even make back your money.
