Consider
Grading Nidoking from 151 is a marginal call rather than an obvious one. The gap between the $0.32 raw price and the $126.25 PSA 10 price gives a 40% Return on Grading. Fine to include as a filler in a batch you're already sending, but not worth a submission on its own.
Among the 78 cards in 151 with PSA 10 sale data, Nidoking ranks 36th for Return on Grading and 41st by PSA 10 price. Of the 13 Rare cards with PSA 10 sales, it is 7th for Return on Grading. The median PSA 10 in this set sells for $131.00. 19 of the 78 clear a 100% Return on Grading.
