Unique gold bar, 'birth certificate' realize $224,200
- Published: Nov 21, 2011, 7 PM
A unique 1832 gold bar from Brazil and its “birth certificate” realized $218,500 during Daniel Frank Sedwick’s Oct. 25 and 26 treasure and world coin auction No. 10.
The price for the piece, which circulated as money, is a record for a South American gold coin, according to the firm, and reflects the 15 percent buyer’s fee.
The auction in total realized an estimated $1,425,000, including a 15 percent buyer’s fee, according to a representative of the firm. The firm did not provide an exact figure.
The bar was accompanied by the guia, or “guide,” which Sedwick calls “essentially its birth certificate.” The guia is an official one-page document produced at the foundry and legalizing the ingot as currency. It bears the owner’s name and ingot’s number, purity, weight and date.
Last offered publicly in 1948, the 39.74-gram gold ingot is a relic from a half-century period when gold bars were made from native-mined metals and used in place of coinage (according to the Spink Numismatic Circular of March 1903, the circulation gold coinage in Brazil was prohibited from 1750 to 1808). They later circulated alongside coinage.
The piece in the Sedwick auction, numbered 114, is one of about a half-dozen surviving examples issued under Dom Pedro II, the last ruler in the Empire of Brazil, as production waned before the practice finally ended.
The ingots were issued to monetize new gold into circulating currency and to make sure taxes were paid in the process. Made from natural gold brought in to official refineries for testing, smelting, marking and taxation, the ingots were typically sent to Europe where they were melted. Today, an estimated 218 genuine examples are known to exist, with slightly more than half of these in private hands, the rest housed in national museums in Brazil, Portugal and the United States.
Rarer still is each ingot’s original guia, which also records the foundry name and bears the signatures of its officials at the bottom to show that the tax was paid. According to Sedwick: “The guia was a fragile and somewhat unassuming piece of paper that was almost always lost or inadvertently destroyed, but it bore the utmost importance in establishing legitimacy and value. Probably fewer than 10 surviving ingots still have their guias.”
The ingot in the Sedwick auction is flat and irregular, shaped like an extended rectangle approximately 69 millimeters long, 11 millimeters wide and 3 millimeters tall. Most of the stamped markings appear on one side, including the arms of the Empire of Brazil, the serial number, date, numbers indicating its weight as 1.375 ounces and 6 grains and fineness as 23 karats (.9583 fine) gold, and an intertwined monogram AAB (for assayer Antonio Avila Bittencourt) within an incuse circle with beaded border. Three ribbed lines in the fields between the stamps are security cancellations to prevent further stamping.
The reverse shows a portion of the round seal for the Serro Frio foundry at the bottom. The seal, being wider in diameter than the width of the ingot, is incomplete, showing only a portion of its design details and the first two letters of the foundry’s name, SE[RRO].
The guias not only provided the documentation confirming their manufacture, but they were required to accompany the ingots, which could be confiscated if not accompanied by the document. As with other guias, the prescribed monetary value (in this case, 17,380 reis) is written on the guia and not stamped on the ingot itself.
The auction also included a collection of dated gold 2-escudo coins of Bogotá, dubbed the Santa Fe Collection.
The collection contained nearly 100 dated Bogotá 2-escudo cobs, representing more than 50 different dates, showing changes of styles and assayers over the 130 years of their production.
A buyer’s fee of 18 percent applies to successful bids, with a 3 percent discount for items above $5,000. Prices listed below reflect the appropriate fee.
