Tribute to the World Tree #373 from March of the Machine is a extended art foil rare card that currently sells for about $12.95 ungraded, with graded copies ranging from $19.99 at grade 9 to $30.00 at grade 10. A grade 10 copy sells for around $30.00, about 2.3× the $12.95 raw price, so high-grade copies are worth grading.
