I don't know much about Disney pins, but it appears some may be collectible.
It's almost impossible to read some of the inscriptions on the backs but I'll give it a try:
1. Pirates of the Caribbean - All that glitters be not gold - Hinged fold out - Bunch of the usual writing, Disney, made in china, etc. FAC-045256-25006
2. Ellie grape soda pin badge - "Pin Trading 2010", "Disney made in china"
3. Remember Me - Coco- "Pin Trading 2017", "Disney made in china". "FAC-036223-17292"
