The Denver Museum of Nature & Science displays artifacts from a sunken 18th-century pirate ship in "Real Pirates," which shows from March 4 - August 21, 2011.
Coins and artifacts recovered from the wreck site of the Whydah, which sank in 1717. Many are on display in the National Geographic exhibition, "Real Pirates: The Untold Story of the Whydah from Slave Ship to Pirate Ship."

Underwater explorer Barry Clifford discovered the Whydah Gally off the coast of Cape Cod, Mass., in 1984. Rather than selling the sunken treasure, Clifford preserved the more than 100,000 artifacts for display in museums. The pirate ship sank in 1717 in a storm, and only two of the 146 men aboard the vessel survived.
