1932 Orbit Gum Pins-How do you grade these?
 

Recently purchased at auction a few groups (42 in total) 1932 Orbit Gum Pins. Have been involved with vintage cards for many years but have never purchased pins. My question is how do you grade these things and what might be the best way to sell (Auction, Ebay) Thanks for any help.
