COLLECTING sports collectibles or sports memorabilia, antique or modern, is limited by two factors: the money available and the space to be filled. Having determined these basic essentials, it is then a personal matter. The taste of the collector may lead to Baseball Memorabilia, Basketball Memorabilia, Football Memorabilia, Golf Memorabilia, NASCAR memorabilia, Diecast Collectibles, Bobble Heads, Hero Posters, or innumerable other things. The lucky acquisition of an admired piece may lead to a determination to get more of the same, or at least to find out what the admiration is all about.

An encyclopedia definition of Sports Collecting would go something like this: "The hobby of sports collecting consists of acquiring specific sports items based on a particular sporting interest of the sports collector. These sports collections of sporting things are often highly organized, carefully cataloged, and attractively displayed." A sports collectible (or collectable) is defined as a manufactured item designed for people interested in sports to collect. The term sports memorabilia usually refers to items related to sporting that can be directly connected to a recent or historical sporting event or sports personality. There are many people that collect these sports memorabilia and collectibles.

Since collecting depends on the interests of the individual collector, it may deal with almost any subject including sports collectible and sports memorabilia. The depth and breadth of the collection may also vary. Some collectors choose to focus on a specific subtopic within their area of general interest, for example Baseball memorabilia of the New York Yankees, Basketball memorabilia of the Los Angeles Lakers, Football memorabilia of the Dallas Cowboys, Golf memorabilia of Tiger Woods, NASCAR memorabilia of Tony Stewart, Diecast collectibles of fire trucks, Bobble Heads for any sport, and posters of heroes such as Lance Armstrong. Others prefer to keep a more general collection, accumulating any or all Baseball memorabilia, Basketball memorabilia, Football memorabilia, Golf memorabilia, NASCAR memorabilia, Diecast collectibles, Bobble Heads, or Hero Posters.

When the NBA, MLB, and NFL began selling their basketball, baseball, and football jerseys in stores during the 1980s, game used jerseys also became a hot item among sports memorabilia collectors. Former NBA player Dennis Rodman was famous for taking off his jerseys and throwing them to the stands after his games were over. Michael Jordan is probably the basketball player whose memorabilia is most sought after by collectors. Todays stars include Ben Roethlisberger, Shaquille O'Neil, Nomar Garciaparra, etc. These players seem to be pushing the already popular area of sports collectibles and memorabilia to a new level of acceptance to the public.

Collections can take the form of a single item such as a signed baseball, football, or basketball. Collections can also take the form of a series of items, such as jerseys from each member of a particular baseball, basketball, or football team. A NASCAR collection of hats from different drivers is very popular. Golf balls with different logos are especially popular. The cost of any sports collectible memorabilia item is directly proportional to the popularity of the sports figure with which the item correlates. The more popular the sports figure, the more money the sports collectible memorabilia item will demand. The whole sports collectible memorabilia industry is driven by supply and demand. The more demand the higher the price and vice versa. Also, the more supply of an item, the lower the price. Sports cards would be a good example. Only so many of certain cards were ever made. Those carry a higher price than those that were made in bulk. Quality is a very big determining factor in the price of any sports collectible memorabilia item. In general, the better the quality, the higher the price.
