 There's the spinners and that's the rubber band, man. So let's talk the Olympics. Do you plan on investing in Olympic souvenirs this summer? I mean, how much of it will actually increase in value? Well, according to sports memorabilia dealers, not much. Because so many souvenirs are made, they're just not a good investment. One of the biggest culprits is Olympic pins. Yeah, the colorful enamel pendants may seem like an inexpensive investment, but a full set of pins can cost thousands of dollars. And worse, their values drop sharply afterwards.
