Surrak, the Hunt Caller #210 from Dragons of Tarkir is a foil rare card that currently sells for about $1.06 ungraded, with graded copies ranging from $6.27 at grade 7 to $26.00 at grade 10. A grade 10 copy sells for around $26.00, about 25× the $1.06 raw price, so high-grade copies are worth grading.
