Back when I began collecting sports trading pins, I used to occasionally come across a pin that had a little something extra, such as sparkly paint, another pin fastened on top of the main pin, or something even cooler – moving parts! These days, a lot of the sports pins I see, especially those from youth sports, feature moving parts. The most commonly found moving parts are called Sliders, Spinners and Danglers. There are also bobbling pins that go beyond the traditional bobble head, and I’ve seen baseball bobbles, bobbling bats and more. Spinners are probably the ones I’ve seen the most of… The pins typically have a spinning baseball, bat or mascot/logo. The spinning portion looks like a miniature pin itself, and it’s fastened with a short post through a drilled hole in the main pin. Seems pretty simple but adds an extra element to the trading pins. Sliders are a similar concept, except instead of spinning, they are attached through a slot, or channel that has been removed and they move across the pin rather than spinning in a circle. This allows simulation of movement, such as a player sliding into home plate, or a baseball moving from the bat to outfield. I’ve collected over a hundred or so of these moving trading pins, and each year they come up with some new and creative way to use the moving parts. One of my favorite resources is Trading Pins US They seem to be the most collectible and popular amongst the kids and us adults who trade and collect them, I guess the idea is who would want a boring old stationary trading pin when you can have one with moving parts? No takers?
