Anybody collect non-sports pin back buttons?
 

Hi .... Does anyone collect non-sports pins?I recently picked up 4 original sales advertising panels with the 50 original pins attached to them and 3 empty panels with no pins attached.They're from 1967 and were made in Greenwich Village New York City.The pins are 1 1/4" inch and the panels are 16 1/2"x 8" inch.
I was hoping someone might be able to help with the values of them.I have a lot of pins covering various subjects,but I've never had anything like these panels before.I know the value depends quite a bit on the pins desirability,but I was thinking that someone here could give me a general idea of the value.
Thanks in advance...Ed (edtiques)
