Night Stretcher #173 from Mega Evolution is a holo ultra_rare card that currently sells for about $4.95 ungraded, with graded copies ranging from $10.50 at grade 7 to $29.99 at grade 10. A grade 10 copy sells for around $29.99, about 6.1× the $4.95 raw price, so high-grade copies are worth grading.
