I ran into these some time ago and they are just awesome. 2 bucks and free shipping. Sure it takes a month or so to arrive, but it's worth it. The pins themselves aren't gold plated. I /think/ they are nickel-free, I haven't had a reaction to them yet and I've been wearing them over two weeks now. They only seem to have 9 left though. So go go go go!
(They may also be cute as buttons or pins on clothes if you don't have holes in your ears or things like that)
