With Tom Glavine being the center of my collection I tend to chase any card I see that is not in my collection (to a certain price limit of course). Same thing for printing plate. Some see them as "cards" but luckily, also a lot of collectors seem to ignore them which makes it a little easier to get my hands on these 1-1 cards (or 4-1 cards as some see them). With Topps Triple Threads out I was able to add 2 more to my collection, meet the Magenta and the Cyan versions !!
Furthermore, I recently got my hands on another 2008 Moments & Milestones plate, a Cyan version as one of the above !
Do you guys chase the printing plates as well for your collection or simply ignore them ?
