Magnezone #GG18 from Crown Zenith Galarian Gallery is a reverse holo holo_rare card that currently sells for about $3.88 ungraded, with graded copies ranging from $10.75 at grade 7 to $39.50 at grade 10. A grade 10 copy sells for around $39.50, about 10× the $3.88 raw price, so high-grade copies are worth grading.
