Jungle Jolteon #4: PSA 9 vs PSA 10

Based on the most recent PSA 10 sale of $3,000.00 on Apr 27, 2026, the crack-and-resub math favors the resub: expected value is positive even at a conservative 15% upgrade probability.

Math favors holding the 9
Jungle #4 Jolteon Holo released in 1999 sits in the vintage WOTC tier where gem-mint premiums above $2,775 are common. PSA 10 populations shrink faster than supply on cards of this era, which is why the upgrade arbitrage stays alive.
