20+ Year Old Rookie Cards Valuable?

Well I purchased these rookie cards a decade or so ago and the Bonds cards used to be worth something and now I believe they are lower than ever. As far as the Henderson and Gwynn, they are good cards but not sure what grade they would get. Should I grade any of these or try to get them signed? Thanks

Maybe ttm and then psa/dna would be the way to go.

2) No

The Henderson would fit nicely into a raw mid grade set.
It appears to be a VG/EX card.
