| by Greg Cohen – Stacks One of the many highlights of Stacks upcoming New York International Sale is a lovely and rare 1830 RA P 8 Escudos of Argentina. This is a key date example of the classic Sunface design, the second rarest date in the series.  This piece hails from the Porteño Collection, a small but high quality offering of Argentine coinage, and displays pleasing original gold surfaces with only light wear. This specimen was uncertified when offered in Heritage's January 2007 sale, and was recently submitted to NGC for encapsulation where it was graded EF-45. In his 1962 work, Argentine numismatist and researcher, Jorge Ferarri was able to track fewer than 10 examples of this date. In Calico's "Onza" book, it is simply described as "Extremely Rare." Even in the current information age, we can only positively identify two examples that have traded at auction in the past five years. These include: the example in the October 2008 Spink-Smythe sale (which later appeared in the Ponterio New York International 2010 sale) and this example (ex Heritage NYINC 2007). Curiously, this date was missing from our (ANR's) sale of the Eliasberg World Gold Collection, Goldberg's sale of the Millennia Collection, our Kroisos Collection Sale, and other important recent sales of quality Argentine coins. While there are probably examples in museums in Argentina, the number available to the collecting public is quite small indeed.  Another stunning Argentine rarity offered as part of the Porteño Collection is an 1836 Rosas portrait 8 Escudos struck in silver. Called an "ensayo" or essay in Hector Carlos Janson's book, research conducted by our consignor shows that the 1836 8 Escudos was supposed to be an 8 Soles piece, and thus the silver strikings (which are nearly as rare as the gold) are the officially struck coins. There are four known examples struck in gold, including the Eliasberg-Clapp coin we offered in the Eliasberg World Gold Collection in 2005. Regardless of whether these are official strikes or essay pieces, they are extremely rare. The last silver specimen to sell at public auction was the AU-50 (NGC) that appeared in the Millennia Collection sale. The Porteño Collection example is sharper than the Millennia coin; unfortunately, it has been polished, and is now residing in an AU Details (NGC) holder. Stack's is proud to be able to offer these rarities to the collecting public—for the advanced Argentine coin collector, this is an opportunity not to be missed. |
