Have you ever wondered why a United States quarter-dollar is called “two-bits”? Or, a half-dollar “four-bits”? Do you know why we call our basic monetary unit “dollar” instead of something else?
Two-bits, four-bits, six-bits and eight-bits make reference to the eight-reales silver coin of New Spain and Mexico. It is also called piece of eight and circulated in the English Colonies and freely in the USA following the Revolutionary War. As a matter of fact, the eight-reales coin was legal tender in the United States until 1857 and was the world’s most used coin at one time. It is the renowned piece of eight that became part of the Spanish Main pirate lore.
The coins minted until 1734 technically, are called a cob coins, because they were originally made by hand stamping “tail ends of bars” or “cabos de barra”, which were sliced as planchets from rudely cast, more or less round, bullion bars which were assayed and carefully weighed. “Cabo” might well have given us the name of cob, although it does mean a lump or small mass (as of coal). The second definition comes from the Dutch “kubb”.
Cob coinage was made at the first mint in the Americas in Mexico City, established in 1535. Authorized by a Spanish Royal Decree dated 14 September 1519 to melt, cast, mark and put aside the royal-fifth of the gold and silver being collected from the Aztecs in Mexico City (Tenochtitlan). He used the palace of Axay catl (father of Moctezuma II) for the task. This may be considered the first foundry of New Spain and of all North America.
When Cortes moved into a home in 1521 in what is today the Mexico City suburb of Coyoacn, he established the second foundry in order to meet the demand for currency and produced “more than 130,000 castellanos”, according to information in documents collected by Francisco Antonio de Lorenzana. “Castellano” (Castilian) was the current coin of the time. These were the first cobs of the New World. The royal fifth was faithfully sent to Spain in the Spanish galleons.
When the Viceroyalty of New Spain was established by Spanish Royal Decree signed by the Queen of Spain the 11th of May of 1535, the Casa de Moneda (house of coin or mint) was formally established. Beginning sometime in April of 1536, according to the best estimates, the first mint of the Americas started coining operations.
Cobs did not start pouring-out into world marketplaces until the reign of Phillip II, after 1556. These crudely minted reales (literally, royals) of silver were undated until 1580 when some were and others were not marked with the year of coinage. The first pieces of eight were struck in Spain, as early as 1497, although it was not until after 1572 that the Casa de Moneda in Mexico City struck them. Before that time, only denominations smaller than eight-reales were struck in Mexico. (more…)

Suppose that this column was geared towards art enthusiasts rather than coin enthusiasts. Would it then make sense to discuss only the paintings that most art collectors could afford? Collectors who cannot afford great and culturally important paintings enjoy learning about them and often learn to apply their knowledge of famous painting to their interpretations of a wide variety of not-so-famous paintings. Likewise, coin enthusiasts, in general, appreciate coins that are great, famous, very rare and/or important to the culture of coin collecting.
Michael Hall has been a prolific collector of art for more than 60 years amassing vast collections with a focus on sculpture. Michael was inspired in his youth by the Kress Collection, a phenomenal collection of medals housed in the National Gallery of Art in Washington that are of artistic importance, not just of historical or archaeological interest. It is therefore unsurprising that the focus of the numismatic part of the Hall collections has always been on the artistic and sculptural aspects of the medals which have augmented his interest in sculpture of all origins and periods.
