One of only 30 Proofs struck. Looking at population statistics and auction records over the last two or three decades, I believe that there are no more than 12-15 Proofs known and only a handful of these grade PR64 or better. This example is a virtual Gem with strong black and white contrast between the frosted devices and the watery fields. There are no significant hairlines noted below magnification; the obverse has a pair of small mint-made lintmarks in the left field and a tiny dark spot immediately above the eagle's left beak. There are no auction records whatsoever for this date in Proof DCAM or Proof UCAM and the last 1872 quarter eagle in Proof to sell was Stack's 8/07: 3125 (a PCGS PR64CAM) that realized $20,700. This coin is tied with two others as the best Proof 1872 quarter eagle graded by PCGS; NGC has graded a pair of PR65's and a single PR66 with Ultra Cameo contrast. Proof gold coins of this rarity and significance are almost never offered for sale except at auction and few coins that I have offered for sale in some time offer the value that this fantastic quarter eagle possesses in spades.
