Iron Crown ex #216 from Temporal Forces is a reverse holo hyper_rare card that currently sells for about $7.64 ungraded, with graded copies ranging from $17.99 at grade 9 to $26.00 at grade 10. A grade 10 copy sells for around $26.00, about 3.4× the $7.64 raw price, so high-grade copies are worth grading.
