1741 regulated gold cob coin may command $100,000

A specimen of regulated gold cob coinage from 18th century Lima, Peru may see $100,000 during Daniel Frank Sedwick’s Treasure Auction 23, slated for May 15-16.

WINTER PARK, Fla. -- In the early years of the United States, a lack of gold coinage forced citizens to utilize an unusual but practical source. Known as regulated gold, these were foreign gold coins adjusted by respected goldsmiths to weights compatible with US dollars.

Eyes on Regulated Gold Coin

One such piece, an NGC-graded XF 40 Lima, Peru, cob 8 escudos is the highlight of an upcoming sale. It is dated to 1741 struck during the reign of Philip V of Spain. It is regulated by Boston goldsmith Joseph Edwards, Jr. (1737-1783) to $15 in circulating value, will cross the auction block in Daniel Frank Sedwick’s Treasure Auction 23. The sale will be held online at on May 15-16, 2018. The auction firm’s low estimate for this coin is $100,000.

“This is a very important piece for both the Spanish colonial coin collector as well as the US collector,” said company president Daniel Sedwick. “Never before have we offered such a significant gold coin; the dual-nation history it represents goes far beyond a simple countermark.”

Historic Doubloon

The coin represents the earliest host for a regulated doubloon as well as being the only known regulated coin with the mark of Joseph Edwards, Jr. Edwards was a third-generation goldsmith from a prominent Boston family. He learned his craft from one of his uncles, Thomas or Samuel Edwards, and became a prosperous metalworker himself. His regulation mark on the coin appears as a simple I•E countermark in a rectangular indent pressed into the weight-adjusting plug. The plug and countermark reside at the foot of the lower-left lion, a seemingly random placement but perhaps chosen so that minimal coin design was lost in the process.

The coin was previously owned by Julius L. Brown, son of Georgia governor Joseph E.
Brown, and was sold as part of his estate in the May 1911 Lippincott, Son & Co. auction.
