Base Set 2 Marowak 52/130: PSA 9 vs PSA 10
Base Set 2 Marowak 52/130 shows an unusually wide gem-mint premium between PSA 9 and PSA 10: a $149 dollar gap, with the gem mint multiplier at 5.8x. Based on the last tracked PSA 10 sale of $180.00 on Apr 14, 2026, the math leans toward holding the 9: expected value turns negative at conservative upgrade probabilities once the resub fee is in.
