The trading value of baseball cards varies significantly based on rarity, condition, popularity and market fluctuations. Following a baseball card trading boom in the 1980s, when card trading transformed from a wide-scale hobby to an expensive pursuit for the serious collector, the industry experienced a massive price slump.
Websites that specialize in the trade, such as Vintage Card Prices or Tuff Stuff's Sports Collectors Monthly, allow fans and collectors to track the value of baseball cards. These sites offer extensive tools for determining the value of a collection. Users can also place classified ads to locate or sell baseball and other sports cards, read blogs and learn about upcoming events where enthusiasts connect with one another.
