Greninja-GX #SV56 from Hidden Fates Shiny Vault is a reverse holo shiny card that currently sells for about $70.00 ungraded, with graded copies ranging from $33.80 at grade 7 to $180 at grade 10. A grade 10 copy sells for around $180, about 2.6× the $70.00 raw price, so high-grade copies are worth grading.
