The very first pieces of sports memorabilia in this country were baseball collectibles, and for obvious reasons. Baseball is America's pastime, and since the 1880s it has captured the hearts and minds of millions of Americans. Because of its popularity, baseball collectibles are almost as old as the game itself.

Even before the 19th century, cigarette companies were making baseball cards of popular players of the day. Of course, now those cards are worth thousands if not hundreds of thousands of dollars. As America evolved in the 20th century, so did baseball collectibles. As more and more Americans became passionate about baseball, the idea of asking for autographs gained momentum. Some of the early sports stars of the 1930s, like Babe Ruth and Ted Williams, were known to offer their autographs to adoring fans in the stadium.

In today's world, the range and diversity of baseball collectibles has exploded. In addition to autographed baseballs and baseball cards, collectors collect jerseys, baseball bats, signed bats, baseball gloves, newspaper clippings and Hall of Fame induction programs, baseball ticket stubs from World Series games, and that's just the start of it.

If you're looking to get in on the action, it's best to know your market before you start spending money. Do your own research regarding what's hot and what is of little value. When it's time to expand your collection, the smart money you save will turn into profit in the long run. Collecting for profit is a long-term endeavor, and you must exercise patience both when buying and selling.
