The Real , or Royal, was a form of currency used by the Kingdom of Spain from the 1300s through the 1800s. This coin is associated with the shipwrecks of the Santa Maria de Yciar, the Esipritu Santo and the San Esteban. A storm drove these three ships aground off the coast of Texas in April,1554 while traveling from Mexico to Cuba. The location of these shipwrecks is now part of the Mansfield Cut Underwater Archeological District.
