Watch List notes:

Santiago, Chile, gold 10 pesos, 1863/2, NGC MS 64-star PL, finest known. KM-131; Fr-45. Deeply struck (the overdate bold) with frosty details against mirrorlike fields that bear strong die-polish lines, all in a lovely yellow color, just a few bagmarks away from the Gem UNC category but rightfully singled out by NGC with a "star" designation for unusually choice appearance, also the only one of its type known in the Prooflike category. Indeed this is a very special coin, probably a specimen or first strike (from the same dies as the next lot), but in any case clearly intended to be superior to regular issues and wonderfully well preserved, just the kind of coin you would expect to have ended up in a world-class trophy collection like Eliasberg or Pittman or Millennia (none of which had anything close in this type), but instead quietly held for a long time by a savvy numismatist, this being its first time on the public market. We often talk about rarity of strike or condition, but the rarity of fresh, unseen material is perhaps an even bigger factor today. A true "wonder coin" for the specialist or trophy collector. NGC #4660427-001.
