DescriptionHB-Unlisted EP-Unlisted 12¢ Trial or Experimental Piece Silver Case Choice About New. Identical to Lot 643 of the Stack's June 2004 sale, but although called unique there, this is a different piece. The stamp is centered differently, the mica on this piece is absolutely perfect, and various diagnostics in their photograph are not present on this piece and vice versa. This piece likely came from the same source as the pieces in the 1968 Herst sale.
Estimate: $6,000 - up.
