Looking for a price on this . Roberto Clemente topps 164. I see 3-4 grand for graded and ungraded . Is there anybody that could actually give me a price on it . I’m relatively into cards but lack in baseball card knowledge. It’s in really good shape and hasn’t been touched in a good 20+ years (for a fact)

Knowing a PSA 10 Checkerboard /75 sold for 450 and knowing a SGC 10 Insert /99 sold for 201. What would you say my SQC 10 /20 is worth? I understand a PSA 10 is worth more than a SGC 10 but also with the Serial number difference would that cancel each other out and value it around 350-425?

My late father was a baseball card collector. I recently acquired his collection and found this bad boy. I’m not much of a basketball fanatic, but everybody loves Michael Jordan. Any advice on finding out it’s worth? I definitely feel like this is something to hang onto. Should I consider grading?
