Diancie #GG13 from Crown Zenith Galarian Gallery is a reverse holo holo_rare card that currently sells for about $2.99 ungraded, with graded copies ranging from $15.37 at grade 9 to $80.00 at grade 10. A grade 10 copy sells for around $80.00, about 27× the $2.99 raw price, so high-grade copies are worth grading.
