This fully struck Premium Gem has blushes of navy-blue and brown on the lower-left reverse, but most of the piece is only lightly toned. Much scarcer than suggested by its proof mintage of 1,000 pieces, since unsold sets were melted. Population: 1 in 66 Cameo, 0 finer (3/22). Ex: October Signature (Heritage, 10/2009), lot 327; Stack's Bowers (10/2016). From The Warren Collection. (Registry values: P3)
