1907 $20 High Relief PR66 NGC....
Dr. Robert Loewinger's useful but underutilized reference on Proof Gold Coinage of the United States (2003) maintains that an "unknown number of satin Proof coins were made by striking six or seven blows of the press. Also there is a sandblast finish of this type." We have numerous times cited the criteria of the Satin Finish proofs that Walter Breen put forth. However, Loewinger goes a step further, actually listing the "criteria used by NGC to distinguish Proof examples of the High Relief edition of the Saint-Gaudens Double Eagle from Business Strikes:
"1) Extreme sharpness in all details, both at the centers and toward the peripheries.
"2) The complete absence of die erosion or distortion.
"3) Numerous, raised die-polishing lines on both sides. These appear in a random, swirling pattern. While also evident on currency strikes, these are particularly bold on Proofs.
"4) Uniformly satiny surfaces, without any of the radial flowlines that produce conventional Mint luster.
"5) A build-up of metal just inside both borders, though especially evident on the reverse. This appears as a slightly raised ridge forming a concentric circle with the coin's border. It probably resulted from the extreme compression to which the Proofs were subjected to by additional strikes."
This piece meets all the criteria set out above. The surfaces glow with bright, satiny mint luster and the striking details are extraordinarily sharp. A fine wire rim encircles each side from the extra blows required from the hydraulic press used to produce these pieces. Simply outstanding presentation and eye appeal.
