I'm sorry for asking what I'm sure is a dumb question, but what do people mean when they say they collect "type cards?".

Type cards are those as designated by Jefferson Burdick when he wrote his baseball catalog. He created the classifications of "R" (Candy & Gum), "T" (Tobacco), "E" (Caramel) and so on. Some type collectors go for one example of every designation in the book, some specialize in just one type.
