Base Set 2 Venomoth #31: PSA 9 vs PSA 10
Base Set 2 Venomoth #31 shows a modest premium between PSA 9 and PSA 10: a $17 dollar gap, with the gem mint multiplier at 1.9x. Based on the last tracked PSA 10 sale of $40.00 on Oct 14, 2024, the math leans toward holding the 9: expected value turns negative at conservative upgrade probabilities once the resub fee is in.

Math favors holding the 9
Where this card lands in the broader Base Set 2 picture: a non-holo with a $17 gap between PSA 9 and PSA 10. The PSA 9 to PSA 10 jump on WOTC-era cards reflects population scarcity at the top grade, not raw print run.
