This rare and important issue was unknown until the 1975 ANA convention. At that time, Walter Breen authenticated the first satin proof 1921 Peace Dollar.
Since then, several more specimens have emerged and, as of September 2007, NGC lists 18 examples in its online Census. This total is undoubetdly inflated by resubmissions of the same coin or coins in the hope of securing a higher numeric grade.In fact, we believe that no more than 10-12 distinct examples are known. Along with their equally rare matte proof counterparts of 1921 and 1922, these satin finish proofs are the only specimen strikings of Anthony de Francisci's beautiful high relief Peace Dollar. The author provides diagnostics to differentiate between satin proof 1921 Peace Dollars from particualrly well-produced business strikes. All genuine satin proofs have the following characteristics. Scattered die file marks, slanting up and down, cross each other in the upper-left field and around the letters in the word LIBERTY. Additional die file marks are in the field in concentric circles. The triangular pellet stop after the word TRVST is in higher relief than that seen on business strike 1921 Peace Dollars. It is also in higher relief than any of the other stops on the satin proofs. The central highpoints are free of the striking softness often seen on business strike 1921 Peace Dollars. Swirling die file marks in the field similar to those seen on the obverse. The rays of the sun are in uncommonly high relief. The item "1921 PEACE $1 NGC PR 64" is in sale since Saturday, September 7, 2019.
