SANFORD, Fla. -

A Sanford family has struck gold for the second time in the past year after finding a gold artifact within a Spanish shipwreck off the coast of Florida.

Rick, Eric, Lisa, Hillary and Lindsay Schmitt found an ornate, high-karat gold pyx in the 1715 Treasure Fleet that sunk off the coast of Fort Pierce.

The Schmitts, along with their partners the Zeak family, say the gold pyx is the second piece of an artifact that was originally found in the same area in 1989. It was crafted in the late 1600s to early 1700s and was used for transporting a Eucharist, according to the Schmitts.

The family found 50 feet of gold chains and many gold coins worth $500,000 in September 2013.

The Schmitts plan to hold a formal news conference on Wednesday to show off the artifact and answer questions about the discovery.
