The "100 Years" and "Magic" pins are the same thing with different designs. They're pretty cool. They go off on rides, during parades, and after shows like Fantasmic. The only bad thing about them is the batteries only last a few days since they are basically radio receivers that are constantly on once you pull the battery tab after you buy them. I think the "Magic" pins are $16, but they still have the "100 Years" pins at the Belz Outlet for $4.
