The Regulated dollar was among highlights that also included coins from the Dahlonega Mint and California Gold Rush.
A Revolutionary War rarity that realized $240,000 led the coins certified by Numismatic Guaranty Company (NGC) in a recent Stack’s Bowers sale. Several NGC-certified gold rarities also realized six figures in the Global Showcase Auction — Session 7 and Session 8, which concluded on August 25, 2022.
The top highlight of Session 8 was an incredibly rare (circa 1780) Regulated dollar — Philip Syng Jr. ‘PS’ on a Bolivia 1751-P eight reales graded NGC VF-25 (lot 7006). The obverse clearly depicts the mark of Philip Syng Jr., a renowned silversmith who was most famous for creating the inkstand used for the Declaration of Independence and the U.S. Constitution. The ‘PS’ countermark dates to the Revolutionary War, when Syng regulated foreign currency to adjust it to local standards. The lot, which also included an unadulterated Bolivia 1751-P eight reales, realized $240,000 in the auction.
The top NGC-certified coin in Session 7 was an 1840-D Liberty Head Quarter Eagle graded NGC MS-62 (lot 6024). The coin’s grade makes it the finest known for this particular issue by the Dahlonega Mint, which was established in Georgia amid a gold rush there in the 1830s. The coin realized $144,000.
