It also has white stuff around the posts

This kind of thing drives us all nuts. Yes, your pin is 100% real and authentic. What you are seeing is not the telltale border of a fake or counterfeit pin. For some reason, some pins with back patterns, DSF, WDI, and others have this "border" and it worries some people. The difference between your border in question and the border on a fake is that on a fake, the border is raised, and it looks like there is a fine pencil line of extra metal that runs all the way around the pin. On your pin back, the pattern just stops and falls short of the edge. I know its confusing, and it is a pain in the rear that Disney started doing this to us, but it happens. For good close up pics of what the raised border on fakes look like, check out two of the stickyed posts at the top of this part of the forum, one started by me and especially one started by IAmDisneyDan. The pics Dan posted show you what a fake border looks like up close so you can see the difference.
