Plush mascots are among the cutest Olympic souvenirs, but they don't hold their value. Mass produced in the hundreds of thousands, they are likely to go down in price as soon as the games are over.
Olympic pins are among the classic souvenirs of the games. Unfortunately, though, they are produced in huge quantities and enormous variety, which means that if you're a collector, getting a full set of pins can run you thousands of dollars. To make things worse, they lose up to 90% of their value within a few months of the games.
Did you know that you can buy an Olympic torch? Sold by both the torch run participants and the Olympic committee, the torches tend to lose value immediately after the games, but can be a good long-term investment if you can wait to buy when prices are low.
Olympic winners' medals rarely go on the auction block, which helps keep prices high. When Tommie Smith tried to sell the gold medal he won at the 1968 Olympics, his asking price was $250,000.
A lesser-known Olympic collectible, "badges" were metal identification tags that were produced up until 1976. Rare and hard-to-find, their prices can be extremely high, and they hold their value. This badge was worn by Doris Storey from the Berlin Olympics in 1936.
