Looking back at top lots of Harmer-Schau’s APS Stampshow sale
By Matthew Healey, New York Correspondent
Here is one of four recent auctions we are recapping in our latest U.S. Auction Roundup:
APS Stampshow, the annual summer gathering of the American Philatelic Society, held this year Aug. 4-7 in Portland, Ore., treated visitors to two major auctions of United States and worldwide stamps.
Harmer-Schau, based in Petaluma, Calif., conducted a sale Aug. 4-6 featuring the Robert Anderson collection of United States special delivery issues.
One of the most closely watched items in the Harmer-Schau sale was a postcard franked with a 1¢ Franklin stamp of the series of 1903, issued imperforate and privately converted to a vertical coil stamp (Scott 314V) in 1908 by an inventor named Layton Parkhurst, for use in his experimental vending equipment.
Connect with Linn’s Stamp News:
Parkhurst, of Indianapolis, was taking part in a Post Office Dept. competition to develop machines that would automate the vending of single stamps to postal patrons.
The first coil stamps provided to him jammed his dispenser. Being a resourceful sort, he asked for and got imperforate sheets, which he converted to coils on a machine he designed for that purpose.
A set of four little pins in the vending machine moved the stamps forward; their indentations are visible at the top and bottom of the stamp on the postcard.
Recently certified by the Philatelic Foundation in New York, the postcard in the Harmer-Schau sale is the only known use of such a stamp on cover, and the earliest example of any government-issued stamp from Parkhurst’s equipment.
The postcard sold for $14,950, including the 15 percent buyer’s premium added by Harmer-Schau to all lots.
Special delivery offerings at the Harmer-Schau sale included some rare Panama-Pacific die proofs of the earliest U.S. express mail stamps.
These were part of a set of small die proofs of 413 previous U.S. stamps printed on soft, yellowish wove paper for the Panama-Pacific Exposition in San Francisco in 1915. Just three to five sets were produced.
In the Scott Specialized Catalogue of United States Stamps and Covers, the Panama-Pacific die proofs have numbers ending in “P2a” and the code “PP” in the description. Despite their beauty and great rarity, most are valued at just $2,500 to $3,500.
One such proof, of the 10¢ blue special delivery stamp of 1888 (Scott E2P2a), brought $2,760, and others did similarly.
It was the second time this year that Panama-Pacific die proofs of special delivery stamps had come to auction; comparable results were obtained at World Stamp Show-New York 2016 two months earlier.
Among other highlights of the Harmer-Schau sale were full sheets of the dollar values of the Presidential definitive series of 1938, also known as the Prexies. The sheet of $5 Calvin Coolidge stamps (Scott 834), well-centered with only minor separation of perforations on the selvage, went for $12,650.
