Alolan Vulpix #21a from Guardians Rising is a reverse holo common card that currently sells for about $4.99 ungraded, with graded copies ranging from $10.50 at grade 7 to $49.99 at grade 10. A grade 10 copy sells for around $49.99, about 10× the $4.99 raw price, so high-grade copies are worth grading.
