Progressive Pinellas county Enamel Tie Lapel Silver pin with chain Atom Palm. Pretty neat type in lots of detail, golfer, fisherman and Atom fishing boat. It's marked in the back but I can't read. It's really small it looks silver, so I'm assuming it probably is. It's got some tarnish on it chose not to polish it. It has an animal and a really fancy keeper in the back with a chain. It's a great pin to add to your collection.
