I have purchased two of the three pins that Merryweather has posted and will say that if it is the same person that I bought the pin from, the pins are legit in my honest opinion.
A safe way to know if her pins are legit, would be comparing them with the same pin purchased directly from Disney.
Even if pins appear to be the same, there still is a chance that it was not distributed by Disney, hence it is not one of the 100 authorized copies as per Abyssinian28's post:
there's a very good chance that it's a scrapper/discarded pin. Workers pick them up from the bins at the factory and steal them, then sell them on ebay.
She has sold the same Sleeping Beauty/Stitch pin 2 weeks ago. I know for a fact that other than the high bidder, 2 people got second chance offers from her as it was discussed on the forum, one of them as low as $29.90 (from her fb).
I don't think her pins come on cards. Now she is selling the same LE 100 pin again. I will keep watching her auctions and feedback to see how many of the same LE 100 pin will go through. She is clever enough to space her listings by 2-3 weeks, so people won't get too suspcious.
I realize that many people bought these DA pins in bulk, but IMO the same seller having multiples of the same LE 100 pin is still curious.
This same seller constanty sells a Lady & Tramp Valentine LE 250 pin, pin # 52345. Long time ago, Judy (tiggermickey) had provided a link to scrapper pics and the same L & T pin was among the scrappers in that picture. Yet, if you check pinpics, there is no scrapper alert for that pin.
If you check the same link, you will see that DA pins were not immune to being copied.

I am not trying to stir the pot or upset people who bought from this seller, but as the title says "Please be careful"
