I think I know the answer but wanted to get the opinion of the group - Series labeling. I have been going through allot of older sets (mainly 90's) and there were many years where they would release the cards in a "Series". So example cards 1-100 Series 1, 101-200 Series 2 and 201-300 Series 3, etc. The cards that I have been going through have been Series 2, but unless I dig into the checklist, I don't know that Series 2 is 101-200. Can we/should be add a note into the Comments section as a quick reference. Even the newer sets like 2018 Topps for example and borken into Series and it might give the set more detail for information to have that there. Again, food for thought.
