I'm into the second month or so of logging all my wantlists and have plowed through 1½ of the 20 monster boxes of tradeable stuff I have. Unless there is a big chunk of the same set, it takes me a whole evening to get through half a row of misc. singles. But I'm also stopping and dropping any card that is missing an image on the site through my automatic scanner. The shiny ones always take some editing.
Some sets (mostly inserts) have been easy to fill in what I have and what I need, but others are just my wants because entering the rest takes extra work. I have no intention of cataloguing the rest of my 275K collection otherwise.
I'm continually entering tradeable inventory. Full want lists are at https://thecollectivemind.blogspot.com/p/baseball-wants.html Use the green tabs to navigate.
Have entered 1994 thru 2021 baseball and 2009 thru 2020 football so far. Don't have many newer than 2020 except A&G in baseball, and very little beyond 2019 in football. My extra hockey is older than that.
