Rated as RRRR by Frank Sedwick and listed as "3 known" in KM, this is the rarest issue of this series. It was missing from Eliasberg and the September 1996 Smith & Daughter sale. When this coin was last offered, in the 1981 Maulme sale, it was described as "the only piece with these assayer initials known to the catalogers. Extremely rare, perhaps unique." Deep orange gold with plentiful luster and a blush of rose-violet toning in the left obverse field. Sharp and well struck, with excellent eye appeal. A natural rim flaw is hidden by the encapsulation above C of COLOMBIA. A little notch on the edge below the date and atop the reverse appears to have been a very deft mount removal, thus inspiring the "filed rims" notation from PCGS. Despite this flaw, its hard to imagine a finer example exists. From the Eldorado Collection of Colombian and Ecuadorian Coins.<p>From Henry Christensens sale of the Maulme Collection, October 1981, lot 121.
