Spring of Whitby, sunk in 1824 off Wabasso, Florida

This wreck has been and probably will always be shrouded in mystery, as we have definite proof of her sinking near Vero Beach (the evidence being a bronze bell with her name and 1801 date of manufacture recovered in 1965), yet admiralty records show she plied the Baltic trade in the extreme northern Atlantic at least until 1826! The material from the wrecksite, on the other hand, being Spanish silver bust-type coins, indicates a date of sinking of 1824. Could piracy have been involved?
