Sandy Shocks ex #159 from Prismatic Evolutions is a holo illustration_rare card that currently sells for about $25.26 ungraded, with graded copies ranging from $23.90 at grade 7 to $104 at grade 10. A grade 10 copy sells for around $104, about 4.1× the $25.26 raw price, so high-grade copies are worth grading.
