João Prince Regent Massive gold Ingot of Vila Rica 1814, Prober #1814-V-2297. 99mm X 19mm, 217.90 grams. Assayer ADS. Ex-Huntington. Kurt Prober's massive research on Brazilian gold ingots produced in the nine Foundries, includes 43 specimens produced at Vila Rica. The vast majority of these ingots range from 20 to 50 grams in weight with four specimens over 100 grams. This ingot being the heaviest of all Vila Rica ingots by nearly 80 grams. Provenance dates back to 1903 where it appeared in Spink & Son's Numismatic Circular. It is quite likely that magnate Archer Huntington purchased the ingot in 1903, eventually endowing it to the Hispanic Society of America in New York City. For the last several decades this specimen has been under commission of the American Numismatic Society (ANS) where it remained on display until 2012 when the Huntington collection of Coins was auctioned at Sotheby's in New York.
In September of 2013, Heritage presented Part II of the RLM Collection which included a 90-gram Sabara Ingot with Guia (realized $199,750). From that description:
Gold Ingots as Legal Tender in Brazil
For a period in the colonial history of Brazil, in addition to coins, gold ingots and bars circulated as legal tender. Legislation was passed to control the circulation of powder gold and to tax it at regional Foundries that were initially established in the 1770's. As the ingots were produced, it received marks that would identify the foundry, year, sequential production number, the assayer's monogram, the finess of the gold, and the weight.
