Identifying fake/scrapper pins help

[MickeyMouseCD524]

I just found an old book of pins and I know a handful of them were purchased off of eBay (didn't know any better at the time) and I don't remember which pins they were. But I was wondering if someone could help to figure out if they're fakes/scrappers. I tried the magnet test but some of the ones I know for a fact are real and purchased directly from Disney are sticking to the magnet. Any help I could get would be much appreciated.
