1908 Baseball fan -metal pins
 

Has anybody ever seen these before? I don't know the size as all I have is the picture.

Somewhere between a nickel and quarter for the fan part, closer to a nickel.

are these worth a trip to an auction to try and pick up?

They look to be in great shape. Usually they are almost black in color. It depends if you enjoy pins and how far away the auction is.

i would probably flip them and the auction is 2 hours away

I'd say they are $125 items. each tops. and not worth the trip unless you think they will go for very little.
