It comes down to a personal choice and what the status of the FS is (opened or not). FWIW, here's my take on FS. Regardless of when they were made 80s up to today I've opened each one I've had. There any been time, again regardless of year, where the cards inside were damaged or cards were missing. To me there is not guarantee that a FS is actually a complete set until I sort it. Then I enter the cards into here and have no intention of using the newest feature (as great of an idea that is for many people). But again, that is me and the choice I made to track my collection.
And I would stress the "Total $" calculation, it means nothing as $ in here are inaccurate.
Tired and trembling
I am descending,
will I have to stay here
and live this life again?
