Brand new to Disney pins! I had mentioned to my husband that I wanted to start collecting them so I can trade them at the parks, and he surprised me for my birthday yesterday with a lanyard and a bag of mixed pins he bought online. He said the lady swore in her email that they are all authentic, but I found one that has a typo on the back (missing the 'O' from "Authentic Official") so now I'm skeptical. I read online that some main ways to identify counterfeit pins was to look for the two little nubs next to the post (should have them), if they stick to a magnet (they shouldn't), typos, weird fonts, and imperfections in the enamel. There were a few that stuck to a magnet, but some of those had the little nubs and look fine otherwise. How definite is that sign? There were some that didn't have the nubs or the nubs were different but they're oddly shaped pins (e.g. Eiffle tower) so wasn't sure if they should still have them. One appears to have small bubbles in the enamel so I'm assuming that would be considered an imperfection? Since I'm so new to pins, I'm nervous to say for sure that any of these are counterfeit/scrappers but I want to figure it out so my husband can go back to this lady and inform her that many were. Are there any other things I can look for as sure-fire signs of authenticity?
