Items that have been in direct contact with a famous athlete can have significant monetary value. Game-used items, such as a ball
Mark McGwire hit for his 70th home run of the 1998 season, sold for $3 million. The most expensive piece of sports memorabilia ever sold was a
New York Yankees baseball jersey worn by
Babe Ruth during his '
called shot' game in the
1932 World Series. It sold for $24.12 million in 2024. In 2016, the ten most valuable
sports cards and memorabilia sold for a record-setting combined $12,186,294. The highest price fetched for an association football shirt is $224,000. The shirt belonged to

Autographed items are nearly always more valuable than non-autographed items. Sports memorabilia items are considered good
investments by collectors, as the industry and prices of items grow rapidly. ==Popular items==
