Single Strike Style Mustard #TG28 from Brilliant Stars Trainer Gallery is a rare card that currently sells for about $1.90 ungraded, with graded copies ranging from $4.99 at grade 7 to $75.00 at grade 10. A grade 10 copy sells for around $75.00, about 40× the $1.90 raw price, so high-grade copies are worth grading.
