I would advise against it. The manu-relics aren't very valuable in the first place, so even if it increases the value by 3X it still may not be worth the cost of grading. UNLESS ... you are a huge Juan Soto fan and you have a PC of Soto and want this addition to your PC protected ... then it's well worth it.
I guess if I saved used tinfoil and used tea bags instead of old comic books and old baseball cards, the difference between a crazed hoarder and a savvy collector is in that inherent value.
