1867 10c green, Z.Grill, segmented cork cancel, well centered on crisp white paper, completely sound, ex-Laurence and Stryker, with 1958 and 2019 Philatelic Foundation certificates (the latter graded "VF-XF 85"). There are only six known copies of this stamp, one of which is in the Miller Collection. Only one other (ex-Ishikawa) is sound and this is by far the better centered of the two. A major philatelic rarity, one of only five existing examples available to collectors, this one not seen since 1958 (Siegel Census 85D-CAN-01), worthy of the finest collection (SMQ for FN-70 $520,000) (Scott catalogue value is for a well centered copy with faults) cat. $600000 (Cat No. 85D) (Image)

Cat. $600000, Est.$750,000
