Here are pictures of my collection of Green Day badges.
These are official pins which came in a package and I got them in 2005.
I also got this badge in '05 and it's an official one. The front of it is made of a soft material.
These badges are custom made and I got them in 2009.
And here are these badges of Billie Joe which are custom made also. I have other Green Day/Billie Joe badges too but I'm only showing these ones that have pictures/designs from the American Idiot era.
