Lower tier grading

I have some lower tier cards, per Collectr App, they are all under $70 as a 10. Would it be worth submitting to BGS and then try to flip as they come back as a 9/10? All are clean fresh pulls. I just got into Pokemon, I'm more of a magic guy.

I can also put them on my booth as I vend. I'm an exclusive Magic booth but everyone walks by, asks for pokemon, one piece or riftbound and then walk away. Trying to hedge a bit so I can spread it out a bit.
