Latest news on RIO2025, the 5th International Convention of Historians and Numismatists, set for Sept. 2-6, 2025 in Rio de Janeiro, Brazil

The 5th International Convention of Historians and Numismatists, RIO2025, is just weeks away. The event will take place in the magnificent city of Rio de Janeiro, Brazil, a city recognized as a World Heritage Cultural Site by UNESCO for its rich history and cultural heritage.

Open to the public, the convention boasts a diverse and stimulating agenda, with lectures by some of the world’s leading researchers and authors, exhibitions, book launches, visits to museums and historical sites, as well as formal and informal social events. In addition, RIO2025 will feature thematic round tables, institutional presentations, specialized workshops, and spaces for academic exchange between researchers, collectors and professionals in the field.

Following a rigorous jurying process, twenty-five previously unpublished academic papers have been selected for presentation at RIO2025, researched, authored and presented by:

Jesse Kraft, PhD, representing the USA; Liesel Gentelli, Australia; Korhaan Mainil, Belgium; Juan Claudio Lechin, Bolívia; Daniel Oropeza Alba, Bolívia; Ana Bustamante Ayala, Brazil; Giovanni Miceli Puperi, Brazil; Pedro M. Zaninetti, Brazil; Alexandre Costa, Brazil; Rogério Bertapeli, Brazil; João Pedro Vieira e Mariana Brum Fonseca, Brazil; Hilton Aparecido Magri Lucio, Brazil; Andrés Felipe Cortazar, Colombia; Maricí Martins Magalhães, Brazil/Italy; Indyra Mendoza, Honduras; Ricardo de León Tallavas, Mexico; Jorge A. Proctor, Panama; Paolo Mario Quenta Loza, Peru; Dr. Glenn Stephen Murray Fantom, Spain; Ana Vico Belmonte, José Mª de Francisco Olmos, and Katharina Nothnagel Vivas, Spain; Ana Vico Belmonte, José Mª de Francisco Olmos, and Patricia Labrador Ballestero, Spain; Mario Alonso Barraco, Uruguay; Javier Avilleira, Uruguay; Daniel Luis Padula Graña, Uruguay; and Hussein Larreal Soto, Venezuela.

Registered RIO2025 attendees will receive a copy of the official RIO2025 Commemorative Medal in their participation kits. The medal’s design was the result of an international competition won by Carlos Alexis Huatuco Nanzer of Peru. Nanzer has established a name for himself in commemorative medal design, as he also produced the winning art for the 2nd and 3rd International Conventions.

For the first time in the Convention’s history, university students have been invited to participate in an academic poster competition. Ten visual format works will be presented at RIO 2025, offering the students the opportunity to share their research and engage in dialog with leading researchers and attendees at the event.

The International Conventions of Historians and Numismatists were launched in 2016 in Potosi, Bolivia, and take place every two years. Potosi 2016 was followed by Arequipa 2018, Cartagena MMXXI, and Santo Domingo MMXXIII.

RIO2025 is being hosted by the Brazilian Numismatic Society (SNB), and organized by a committee helmed by SNB President, Bruno Pellizzari and ICHN co-founder Daniel Oropeza Alba. Founded in 1924, the SNB is a century-old non-profit institution dedicated to the promotion and development of numismatics. It has a long history of collaboration with cultural and academic institutions, organizing events of both national and international significance.

This year’s congress brings together leading historians, numismatists, academics, minting companies, and auction companies from more than 30 countries. Among a “Who’s Who” of eminent international sponsors, Heritage Auctions, Sedwick & Associates, and Stacks Bowers represent U.S.-based contributors to the event.

Sedwick Auction 37: Record Prices in a Market for the Advanced Collector

10 May

Sedwick Auction 37 delivered exceptional results, marked by record-breaking prices for standout rarities and a stellar performance by the Almenara Collection of gold coins from Potosí and Lima. With finest known examples, multiple provenances, and strong historical significance, these colonial treasures drew intense bidding, reaffirming the market’s focus on rarity, condition, and pedigree.

The results confirmed a trend we’ve observed across recent sales: this is a market driven by knowledgeable and discerning collectors—those who seek out the most important pieces and are willing to compete for them. From rare milled coinage to hand-struck cobs, buyers responded strongly to top-tier material. Shipwreck coins continued their momentum, with rising prices across the board and sustained interest from collectors who value both history and preservation.

At the same time, Auction 37 offered meaningful opportunities for new and mid-level collectors. Strong bidding across a range of price points demonstrated that there is still room for growth and participation at all levels, making this auction a success not only for established specialists but also for newcomers with a passion for numismatics.

This auction also marked a special milestone—it was the first time we hosted a live sale in our new offices. The in-house event brought together collectors, consignors, and guests for an exclusive and memorable experience.

Over the course of six sessions held from May 7 to 9 at our offices in Maitland, Florida, the following highlights unfolded:

Given the exclusive nature of our auctions, now is the perfect time to start thinking about consigning your collection or select coins for future sales. We thank our consignors and bidders for continuing to choose Sedwick Auctions. More great things are coming soon!

The Great Cob Collector: Luis Roberto Ponte Puigbó

13 Oct

We are honored to present the second part of the remarkable collection of Luis Roberto Ponte Puigbó, focusing on rare 4 reales and 8 reales cobs from Lima and Potosí. Luis Roberto’s passion for South American cobs was unmatched, and his collection reflects years of dedication to acquiring some of the finest and rarest examples. It’s a privilege for us to now offer these exceptional pieces to collectors around the world.

In this publication, we also share a tribute from his brother, Alejandro, which beautifully captures Luis Roberto’s love for numismatics and the legacy he leaves behind.

Luis Roberto Ponte Puigbó

Luis Roberto Ponte Puigbó
17/04/1962 – 14/03/2023

“Born in Caracas, Venezuela, descended from an ancient lineage linked to the culture, history, and science of his country, he was a passionate numismatist and historian, a respected lawyer, graduating with Honors from the prestigious Universidad Católica Andrés Bello in 1986. He pursued his profession successfully and brilliantly, being one of the best lawyers in Venezuela, legally representing major companies of the country, demonstrating his dedication and commitment to excellence. His legal background, combined with his passion for history, provided him with a unique and valuable perspective that he applied both in his professional life and in his personal interests.
“Numismatics fascinated him so much that he became an eminent researcher and one of the most outstanding collectors in the world, with vast knowledge of macuquinas (cobs), Hispano-American mints such as Lima, Potosí, and expertise in Venezuelan coins. He presented countless conferences, publications in national and international forums, contributing significant discoveries to this world. He served as Secretary and Legal Advisor of the Venezuelan Numismatic Society. He was a Corresponding Member, Secretary, and Legal Advisor of the Venezuelan Numismatic Society (Sonuve); Lifetime Member of the American Numismatic Society (ANS); Corresponding Member and District Representative for Venezuela of the American Numismatic Association (ANA); Member of the Spanish Numismatic Association (ANE); Member of the Numismatic Association of Chile (ANUCH), Member of Colombian Numismatists (Numiscol); Member of the Philatelic and Numismatic Circle of Barcelona (CNFB); Corresponding Member of the Federal Institute of Numismatic Researchers of the Argentine Republic (IFINRA); Number Member of the Dominican Numismatic Society (SND); among others.
“Luis Roberto dedicated the last years of his life to meticulous research in the historical archives of the Indies in Seville, Spain, leaving several of his findings in progress, which will be published in the near future. He was not just a coin collector; he was an investigator and explorer of the past. Each coin in his collection told a story, which was a small piece of the puzzle of our civilization. As a historian, his insatiable curiosity and meticulous attention to detail allowed him to delve into the mysteries of the past in a way that few could. Luis was always an exemplary, virtuous, cultured, brilliant, dedicated, and enthusiastic human being, whose generosity, simplicity, and humility transcended in all those who had the opportunity to know him. Despite the sadness we feel, he will be remembered for his love of life, his dedication, and passion for history and numismatics. His loss is irreparable, but his legacy will endure for decades in his research, his coins, and in our memories.”

ALEJANDRO LUIS PONTE PUIGBÓ
