"AFAIK, the term goes back to the coin business. There are coin holders made of plastic (vinyl or PVC) that are 2x4 inches, with a pocket on each side. Typically a coin goes in one pocket and a card with description, grade, etc goes in the other pocket, then you fold the holder in half so it's 2x2. The holders are called "flips" because you can flip them open. Eventually the card itself came to be called a flip. By extension, anything with a coin's description and grade came to be a flip. And when card grading came into being, by the same company that was doing most of the coin grading (PCGS-->PSA), the analogy was obvious. Bill T."
