Consider
Pikachu #49 from Silver Tempest sits in borderline territory for grading. Raw copies trade around $0.51 while PSA 10s sell for about $119.00, a 31% Return on Grading. A 9 instead of a 10 would likely wipe out the margin here, so be honest about condition.
Among the 83 cards in Silver Tempest with PSA 10 sale data, Pikachu ranks 9th for Return on Grading and 10th by PSA 10 price. The median PSA 10 in this set sells for $46.25. 3 of the 83 clear a 100% Return on Grading.
