Charizard #SWSH066 from SWSH Black Star Promos is a reverse holo promo card that currently sells for about $51.78 ungraded, with graded copies ranging from $19.00 at grade 7 to $200 at grade 10. A grade 10 copy sells for around $200, about 3.9× the $51.78 raw price, so high-grade copies are worth grading.
