The first is the demand for the player or team representing your keepsake. If you specialize in baseball collectibles such as cards, then you want to make sure you're paying a fair price for them.

When considering the price of any baseball collectible that has to do with a certain player, make sure you know his record and statistics. Is he in the Hall of Fame? Did he shatter other players' records as he made his way to a top spot in the sport?

Rookie baseball collectibles may not give you the comfort you want in knowing for sure how valuable the keepsake will be. While it can be somewhat risky to invest in a piece of rookie memorabilia, it might also give you a chance to greatly profit from your initial investment.

Of course, you're always going to find value in a baseball collectible from a player such as Mickey Mantle or Roberto Clemente. Any player that has become an idol for baseball fans is a good pick for your memorabilia treasure trove. For team collectibles, the Yankees have more people seeking their collectibles than any other team.

The condition of the baseball collectible is another important factor in its price and value. A card in mint condition that has been cared for will fetch more than a card that's bent or has a smudge on it.

Another aspect of what makes a baseball collectible priced right is whether or not it's a hard to find or limited edition. If something is mass-produced, then it will decrease in value.

Probably most important is the "you" factor. What is this particular baseball collectible worth to you? Is it something you just have to have - an item you've been searching for and finally found? Or is it something you could live without?

Baseball collectibles, like memorabilia in any other sport, have price tags based on demand, value to the current owner, and value to prospective buyers as well. Make sure you do your homework with a published price guide to compare how an item is priced for you versus what it's selling for around the world. With today's access to online auctions and dealers, you might be able to find the item you want at a price you can afford.
