Early on the morning of July 31, 1715, an event took place along Florida’s east-central coast that shook the royal courts of Europe.

Among the latest finds over the summer: 200 silver coins, a flintlock, an unusual tan vase and a mysterious set of bronze keys, according to a news release from 1715 Fleet – Queens Jewels LLC.

While the exact ship carrying the onion glasses remains unknown, the vessel was a part of the 1715 Treasure Fleet, Florida Department of State Director of External Affairs Mark Ard told USA TODAY.
