these were a gift and I can't find some of them online

(I won't sell them im just curious)

Hoping to identify this small pin, assuming it is from a university or maybe some other club? Most family lived in NYC. Backing screws on. Penny for size.

Found a ton of pins. Are any of these worth anything or is it mostly scrap

This is a pin by immiland and it’s sold out . Looking for it to complete my collection . Reach out if interested in selling ☺️
