Are you a boxing fan? Those who enjoy boxing often times enjoy collecting memorabilia associated with the sport. From autographed gloves to “fight worn” trunks, there are many items you can add to your collection.

Believe it or not, some pieces of boxing memorabilia are worth hundreds of thousands of dollars. Here are five items that any collector would love to add to his or her collection:

1. Muhammad Ali fight gloves vs. Zora Folley. This may not have been the biggest fight of Ali’s career, but the gloves he wore that night were sold at auction for $29,900 in 1997. Imagine how much these are worth today.

2. Joe Frazier robe from the “Thrilla in Manilla” fight against Ali. On October 1, 1975, Frazier wore this robe in the ring against Ali. This was one of the most memorable bouts of all time, which is why the robe fetched $40,000 at auction.

3. Muhammad Ali trunks from the “Rumble in the Jungle” fight against George Foreman. This fight saw Ali win back his title, and will forever be known as one of the greatest of all time. The trunks he wore sold at auction in 1997 for $57,500.

4. Muhammad Ali robe from the “Rumble in the Jungle.” If you thought the trunks were expensive, consider this: the white robe that Ali wore when entering the ring sold at auction in 1997 for $156,000.

5. Muhammad Ali trunks from the “Fight of the Century” against Joe Frazier. In March 1971 this battle took place at Madison Square Garden. This was the first time Ali would lose as a professional. Despite this, his trunks were sold at auction in 2011 for $173,102. These trunks are believed to be the most expensive piece of boxing memorabilia ever sold.

As a boxing enthusiast, owning one of these pieces of history would be like a dream come true. As you search local estate sales and the internet, you never know what you are going to find!
