Released in the Pirates line and retired after a US-limited run, Treasure Chest, set 1788, contains named characters like King Kahuka and Captain Ironhook and draws collectors from both Pirates and Islanders niches, and its regional scarcity and unique chest packaging support durable demand while also leaving supply-driven volatility.
