Important early coins of Mexico and Brazil from the unparalleled Tyrant Collection ( will be publicly displayed together for the first time at the Long Beach Coin, Currency Stamp & Sports Collectible Show (, February 2 - 4, 2023.

Entitled Tyrants of the New World, this will be the latest multi-million-dollar exhibition in a multi-year series of different displays of portions of the extensive and unprecedented Tyrant Collection. Owned by Southern California collector Dan O'Dowd, it is described as the world's most valuable rare coin collection in private hands.

The big exhibit will be divided into two distinct sections: The Tyrants of the Amazon and The Tyrants of Lake Texcoco, explained Ira Goldberg President of Goldberg Coins and Collectibles, Inc. ( in Los Angeles, California. Goldberg is one of the numismatic professionals providing guidance in assembling the wide-ranging Tyrant Collection of superb quality, historic U.S., world, and ancient coins.

There has never been such an important public exhibit of Latin American coins in Southern California, he stated.

The Tyrants of New World display showcases how Latin America was divided between the Portuguese tyrants who ruled Brazil and the Spanish tyrants who ruled the rest of Latin America.

The Tyrants of the Amazon is a collection of coins issued by the tyrants who have ruled the Amazon. The objective of this portion of the set is to find the biggest, nicest looking, highest condition portrait gold coin for each tyrant.

The Tyrants of Lake Texcoco collection is a type set of coins from the Mexico City mint. The objective is to find the finest representative of each coin denomination for each tyrant there. If there is more than one major coin design in a reign, then there is a representative of each denomination for each major design.

The coinage from the many Spanish royal mints in Latin America were all very similar, explained Goldberg. The Mexico City mint was chosen because it is the oldest and most productive Spanish mint in Latin America.
