Olympic pin trading is going full throttle. The tradition actually began in Athens, the birthplace of the Olympic Games. Now, hundreds of pin trading fans from all over the world are swapping the popular souvenirs.
"Pins started out as a means of identification for people, for example, athletes would have their country pins," says pin trading expert Al Falcao.
The pin trading center has been set up at every Olympics since the 1988 games in Calgary.
Some of the hot new designs this year include Coca-Cola's "Pin of the Day" series.
