I haven't updated my spreadsheet in almost 9 months. During that time there has been so many high end releases to finish out 2018 along with a small sample of cards for 2019. It is a goal of mine to eventually get caught up and I am hoping that maybe around July I will have a fully functioning checklist of all the cards in my collection.
Another item I have been trying to keep up with is Cutch 1/1s equal to homeruns he had with that team.
Here is how the homerun tracker breaks down
PreMLB debut 43
He also hit a HR in the 2015 All-Star Game
Here is another one of my 1/1 cards of Cutch so far as a Phillie.
