A small back story to my question. Every trip we take, we make our way to the Japan pavilion in Epcot for pick a pearl. This particular souvenir is for our daughter and I have a long term plan for her collection. Eventually, she will grow up and get married. These pearls that we collect over the years will then be made into so form of jewelry as part of her "something old" whenever that day happens. We now have a boy and by the time we go on our next trip he will be old enough that I would like to start some sort of collection for him that will last over time. Any suggestions on what that should be? Pin collection, or press penny collection?
