Historians, numismatists, researchers and academic professionals from around the world have come together in Cartagena de Indias, a city declared a World Heritage Site since 1984 by UNESCO, from December 1 to 5, 2021 to celebrate the "3rd International Convention of Historians and Numismatists".

This continental event, now in its third iteration, unites more than 22 countries around the study of currencies, allowing a robust network of specialized researchers to share valuable information and new findings that rewrite the economic and numismatic history of our territories.

The fruits of the third international convention are beginning to germinate with important research and publications such as the book "A Contemporary Review of Potosi and Lima Mint Coins and Assayer History From the Mint Openings up to 1622", written by our researcher friend Carol Tedesco, who through a wonderful and meticulous work shares with us important numismatic events of the Potosi and Lima coins minted up to 1622...

Ing. Andrés Cortázar M



As a foremost authority on Spanish Colonial coinage from the lost 1622 Tierra Firme fleet, Carol Tedesco has provided an up-dated history of the mints and assayers represented on over 200,000 silver coins excavated from the Nuestra Señora de Atocha and Santa Margarita shipwreck sites. Her meticulous study stretching over the last three decades has been augmented by several prominent Latin American archival historian/numismatists who, in the spirit of advancing the body of knowledge, have contributed significant research data to fill in known gaps in the New World coinage. This numismatic "tour de force" is a major archaeological contribution in the documentation of the 1622 artifact assemblage, which tells a unique research story of underwater discovery to be enjoyed by history buffs, academic scholars, and numismatists around the world interested in the Spanish Colonial maritime cultural heritage of the Americas.

Book cover for "Treasure Coins of the Nuestra Senora de Atocha & the Santa Margarita by Carol Tedesco

In just 40 succinct pages, Carol Tedesco's Treasure Coins of the Nuestra Senora de Atocha & the Santa Margarita answers all the most frequently asked questions about shipwreck recovered treasures, including what the coins look like when first discovered, how they are cleaned , conserved, and graded, what they were worth in the 17th century, the meaning of the various markings, and the names and periods of office of many of the men who made them. Of particular interest to "cob" coin enthusiasts is a section devoted to the exceedingly rare Old World minted coins discovered on the Atocha and the Santa Margarita.

Cover of the book "Oceans Odyssey 3"

Chapter 6. Tedesco, C., The Deep-Sea Tortugas Shipwreck, Florida: the Silver Coins.

In 1990 Seahawk Deep Ocean Technology of Tampa, Florida, commenced the world's first robotic archaeological excavation of a deep-sea shipwreck south of the Tortugas Islands in the Straits of Florida. At a depth of 405 meters, 16,903 artifacts were recovered using a Remotely-Operated Vehicle. The wreck is interpreted as the Buen Jesus y Nuestra Senora del Rosario, a small Portuguese-built and Spanish-operated merchant vessel from the 1622 Tierra Firme fleet returning to Seville from Venezuela's Pearl Coast when lost in a hurricane.


Oceans Odyssey 3 introduces the shipwreck and its artifact collection ranging from gold bars to silver coins, pearls, ceramics, beads, glass wares, astrolabes, tortoiseshell, animal bones and seeds. The Tortugas shipwreck reflects the daily life of trade with the Americas at the end of the Golden Age of Spain and presents the capabilities of deep-sea robotics as tools for precision archaeological excavation.

Cover of book "After Life - Images from the Key West Cemetery" by Carol Tedesco and Roberta De Piero

In After Life - Images from the Key West Cemetery with photographs by Carol Tedesco and Roberta DePiero and narrative by Jane Newhagen, we have fresh proof that death can be every bit as splendid as life. These images are evidence that the business and the architecture of mortality in Key West's last resting place, replete with tropical sparkle and haunting idiosyncrasies, make the afterlife as immortal, as uplifting, and as purposeful as life at its prime." 

Mark Howell, author, reporter, editor

In 2020, more than 25 Key West area photographers contributed to “Isolated Island – The Key West COVID-19 Spring of 2020,” a 352 page photo-book produced by Roberta DePiero, Carol Tedesco, and Eric Grahl that documented the first months of the COVID-19 pandemic, when a quarantine checkpoint near the entrance to the Florida Keys was in effect.

In the book’s foreword, arts advocate Rosi Ware wrote, “Many of us exalted in the newfound peace and clear blue waters, the cacophony of bird song and masses of butterflies, whilst others worried about putting food on the table and paying the rent.” The sold-out limited edition run of 1000 copies raised $60,000.00 for Sister Season Fund, lending much needed support to their mission to prevent homelessness and provide assistance for Key West tourist industry workers at that crucial time.
