This summer, philatelists will have a chance to snag the rarest US stamp ever: the 1868 one-cent “Z-grill.”Interested? On June 14, the one-cent Z-grill will be put up for sale by Robert A. Siegel Auction Galleries, marking the first time the rare stamp has been on auction since 1998. Of the two known copies of the one-cent Z-grill, one is held by the New York Public Library. That leaves only one one-cent Z-grill available to private collectors. “There’s multiple stamps that’ll bring $500,000 or $750,000, but the (one-cent) Z-grill is the star of the show,” Shreve said.
