Pin Trading is very popular in Little League Baseball. Attend any of the regional games or the Little League World Series and you will find tents set up to accommodate pin trading. Many Districts across the county and the world have their own individual pins and are eager to swap. In Williamsport most of the ushers get together and design pins each year as do ESPN Cameramen, Security, and most participating teams.
This forum if for anyone who wants to try to do some off season trading or to chat about pins in general.
