I have some Pins and Buttons I would like to add to the database. In my search I found @145 entries for these items in Baseball alone. Since most have no packaging information, I guess I must go by title. I see them from card companies, food issues [to include other issues ex Hardware Stores, MLB and some undetermined issues. Checklists will be a challenge of course. In my Other Collectibles Guide notes, I noted that Pins and Buttons are acceptable as long as they follow criteria already in place. So am I good to go?
