That's cool Ray...I like that a lot. My COVID boredom bred a project where I finally started putting my junk wax into binders...first up was the 81-90 Donruss...those stickers would have helped instead of me constantly adding to 9...although with all those cards put into binders I now have every "9" number up to 700 memorized!!
Yeah on the omitted numbers. 53 is a set I have yet to work on, but the 55s and the 61s can be confusing...but thankfully the unused numbers are at the back end.
