From the research desk

A mid-grade piece of eight from the 1641 wreck of the Nuestra Señora de la Concepción, struck at Potosí and still carried in its original numbered salvage flip. The cross side reads strongly; the flan is light at 21.11 g, the ordinary arithmetic of three centuries of corrosion on the Silver Bank reef. Honest, documented, and priced as the raw coin it is.
