This legendary error is then crowned by the signature of Stephanie Sabin, the former President of PCGS, creating an unparalleled trifecta of rarity, perfection, and insider provenance.
A Design Transformed by a Minting Anomaly
While the coin features the classic designs of Augustus Saint-Gaudens' Liberty and Miley Busiek's Family of Eagles, the "Unfinished Die" error transforms their appearance into something entirely new. The fields, which should have a uniform satin luster, exhibit patches of mirror-like reflectivity. The devices, which should be sharp and frosty on a proof, have an incomplete, ghostly cameo effect. This unique visual texture makes the familiar design feel mysterious and new, offering a glimpse into the coin-making process itself.
