I don't look at my cards thru the lens of value or what they may go for on the market. With that said, I bust open anything slabbed, encased, graded, etc. I won't pay a premium for this cards as it is so I have no qualms freeing them from any plastic prison they are in. Mind you, some of the encasing is more for shipping purposes than anything else.
I don't have any factory sets either, I bust them all open. Example, I got my 2023 Topps set and as soon as I got it, broke it open and sorted it as I see fit. Others would throw a conniption with the thought of it being opened...ruin its future "value". Value to me is enjoying what you have. Collector, not investor.
When the sky is coming down
When you feel like you're going to drown
When you know the end is all that you've been looking for
When the pain is too much to bear
When there's no one who will care
