Night Stretcher #173 from Mega Evolution is a holo ultra_rare card that currently sells for about $4.62 ungraded, with graded copies ranging from $10.50 at grade 7 to $15.58 at grade 10. A grade 10 copy sells for around $15.58, about 3.4× the $4.62 raw price, so high-grade copies are worth grading.
