Need opinions: Is this a good trade?

I'd probably be keeping the Jordan if that's yours already.

Pop113 is not that low but it's MJ. Goes for $75-140usd

If the Kobe is not the Silver Prizm version - prob $30, if it is, maybe $60. Wembanyama who knows - about $30 maybe? Stick with the reputable grading co.
 
Keep the MJ. The Topps Now Wemby has a print run of just under 114,000. There will always be available copies of that card.

It's like that Olympic trio card of Steph, KD & LBJ has a print run of over half a million. You'll be able to pick them up on COMC for under a $1 at some point probably.
