Consider
Shinx #91 from Fusion Strike sits in borderline territory for grading. A 33% Return on Grading comes from the spread between $0.05 raw and $119.99 graded. A 9 instead of a 10 would likely wipe out the margin here, so be honest about condition.
Among the 94 cards in Fusion Strike with PSA 10 sale data, Shinx ranks 18th for Return on Grading and 19th by PSA 10 price. Of the 10 Common cards with PSA 10 sales, it is 3rd for Return on Grading. The median PSA 10 in this set sells for $55.70. 11 of the 94 clear a 100% Return on Grading.
