1910, 1¢ green, Singer Private Perforations, vertical pair with perf. 12 perforations that match the Covel perforations, imperforate between, cancelled by duplex, fresh and Very Fine.Scott No. 385 var. Estimate $100 - 150.
Singer was an old-time New York stamp dealer who claimed to have found an entire coil of the perf. 12 vertical with every other stamp perforated. He also had several on cover to show that they were genuine. Eustace Power was interested in buying the whole lot but he in turn sold it to the Economist Stamp Co. They were then advertised at very fancy prices and a good many were sold. When it later appeared that they were fakes, Economist advertised that fact and offered a fill refund on every pair bought from them; and many were returned. This postally used pair is probably one of those used by Singer to prove their validity.

In the early 1920s, Mr. J. Hull Wilson bought sheets of imperforate stamps and cut out blocks for resale. He then perforated the leftover scrap and remaining sheets with a sewing machine. Most of the stamps were used for his own correspondence. In the late 1920s, Wilson borrowed money from a Pittsburgh bank and put up his bulk of perforated stamps as collateral. When he defaulted on the loan, the bank sold the entire remaining lot to Nassau Stamp Co. Later Herman Herst Jr. acquired a large lot, authenticated these stamps by signing on the backs in pencil.
