Jungle Exeggcute #52: PSA 9 vs PSA 10
Jungle Exeggcute #52 shows a meaningful PSA 10 premium between PSA 9 and PSA 10: a $29 dollar gap, with the gem mint multiplier at 2.6x. Based on the last tracked PSA 10 sale of $46.00 on Feb 23, 2026, 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
Jungle #52 Exeggcute released in 1999 sits in the vintage WOTC tier where gem-mint premiums above $29 are common. PSA 10 populations shrink faster than supply on cards of this era, which is why the upgrade arbitrage stays alive.
