They all did have holes in them, and it was so you could either wear them using either a string around the neck or with a safety pin to show your team support. I can still remember opening the packs from my parents shop ( they weren't sealed) and shuffling cards so I got the whole set with no doubles. My only regret is throwing away the wrappers. I have only kept the Dragons players and other players that rated in the top 100 as per 2008.
They still rate highly in my PC of favourite cards due to the childhood memories.
