It explains why most of us grew up with a phase of collecting some type of trading cards. Nowadays there are thousands of different types of trading cards that span across sports, video games, films, TV series, comics, and well the list goe's on. This is when trading cards really began to branch out as companies began to see trading cards could hold value as vintage items and collectibles. Historically, trading cards didn't get much public attention until baseball cards began to make a rise in the early 20th century. Trading cards have always been a fun way to collect and invest yourself in a hobby.
