Yes, I have done this.
I have done it more than once in the Topps era quest.
Yes I might do it again.
Funny one of the more extreme cases was involving the same player as yours.
I bought a 1915 CJ Sam Crawford, slabbed by SGC (my preference TPG)
This was after checking my spreadsheet and seeing that I needed it...
It was a nice card, and fairly expensive for my modest budget.
Later I find that my spreadsheet didn't account for the small stack of PSA cards I had , and yep...I already had Wahoo Sam in 1915 PSA.
Getting old has its advantages too, (not just disadvantages) since I found a few other cards that I forgot I had that same day...it was like Christmas in July!
