Auction Detail

mint vertical pair (positions 48, 58) with top stamp the variety, top stamp also has "Panama" overprint split (20.9a), bottom stamp with varieties including "Panama" reading up at right (20.4), double diagonal stroke in right "N" of "Panama" (20.5), two "Panama"s close together (20.8), and misplaced entry of basic stamp (20.12), fine and scarce pair, 1990 Philatelic Foundation certificate (Scott $200 for 20b)

mint single (position 78) reading "cts. 8" instead of "8 cts." due to horizontally shifted surcharge, this shift also causes the two "Panama"s close together variety (20.8), lightly tropicalized gum very fine, this is the discovery example of this error published by James Crumpacker in the Canal Zone Philatelist (Vol. 38, No. 3) and subsequently the basis for the Scott catalogue listing, we know of at least one other example from the Bates collection (Scott unpriced)

mint block of four (positions 24-25, 34-35), the "8 cts." surcharge is from positions 23-24, 33-34 as the overprint was shifted horizontally, therefore the right two stamps do not exhibit the 3mm spacing between "8" and "cts." variety (20.6) as one would normally expect on the fifth vertical row, very fine and rare, these stamps originate from the same pane that produced the "8 cts." double error (20d), a full explanation can be found in the Canal Zone Philatelist Vol. 38, No. 3

mint horizontal pair (positions 54-55), left stamp the variety, lightly tropicalized gum, very fine and scarce with just 392 issued, 1990 Philatelic Foundation certificate 

single used alongside pair of 1906 2c on 1p Lake (17a), tied by August 22, 1906 Cristobal duplexes to cover to Gore, New Zealand, few trivial creases do not detract from the appearance of this remarkable cover, one of just two examples of this error on cover, a gem of Canal Zone Philately which has not been on the market in over 25 years, 1995 Philatelic Foundation certificate (Scott $2,000 for used)
