I used to collect Disney Pins, and that was the most stressful, time consuming and expensive hobby I've ever taken part in.
I'd suggest either picking up shadow boxes and backing them with some kind of foam core material with a velvet or cloth cover, so you can stick the pins into it. You can also get deep frames and do the same thing, and just matte around them so they dont touch the glass.
There are lots of Star Wars pins out there, plenty from each year of the SW Weekends, regular Disney Exclusive Star Wars pins (characters, etc), a bunch from Pin USA and many others. I have the boxed pins as well as the two framed sets from Pin USA, and they are quite nice
