Travel 8 months ago Share Tweet Pin Share Captain William Thompson, along with his ship, The Mary Dear, was tasked with the responsibility of keeping Spanish treasure safe during revolts in 1820. He got greedy, killed the Spanish guards, and buried the treasure. His crew was executed, but he was spared and expected to give away the treasure’s location. Thompson said it was buried on Cocos Island near modern-day Costa Rica. When Thompson landed on Cocos Island, instead of leading the Spanish to the missing treasure, he sprinted into the forest never to be seen again. Not much is known after that, but the treasure is estimated to be worth around $200 million. Bonus: Want to stay up to date on our latest Rare Norm news ?
