Collecting baseball cards isn't what it used to be, but for those that do it, it can be quite lucrative. A lot of factors affect the value of a card. Printing errors and small print runs are a given. However, if the player was involved in a scandal, it can affect the price, too. How the public perceives a player can influence a card's value.
If you're a collector of cards from the 1960s and earlier, however, you needn't worry about scandal ruining your collection - too much time has passed for that to be a factor. But the condition, number of cards produced, and the number of cards still in existence will always be a factor.
When a card is officially graded, it is done so on a scale of one to 10, with one being the poorest condition and 10 the best. Of the cards on our list, there are not many that have been found that are a "10," also known as "gem mint." If they do exist, one of these rare cards could be valued in the millions. Check out the most valuable baseball cards below. Hopefully, you're sitting on a long lost "gem" yourself!
